    Hypothalamic-pituitary dysfunction and thyroid gland cytomegalovirus inclusions have been described in patients with the acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC). We evaluated 80 patients with AIDS or ARC for the frequency of hypothalamic-pituitary or thyroid gland failure and altered serum thyroid hormone levels due to nonthyroidal disorders. One patient had subclinical hypothyroidism. Of these patients, 60% had low free triiodothyronine (T3) index values and ...

    MR findings have been reported on the acquired immunodeficiency syndrome (AIDS) demential complex, but the findings are late relative to clinical signs. This paper reports on a new MR finding observed in patients with human immunodeficiency virus (HIV)-related cognitive impairment studied early in the disease process. Fifty-two patients had a total of 86 MR images. Al images were obtained with a 1.5-T system (protondensity, spin-echo, TR/TE = 2,000/30 [repetition time/echo time, msec]). High-signal lesions were seen in the region of the splenium of the corpus callosum and in the crura of the fornices. The lesions demonstrated no contrast enhancement with Gd-DTPA. Pathologic examination was performed in four patients. The fornix-subcallosal abnormality may have relevance to the memory dysfunction in patients with HIV-related cognitive impairment

    A frequent complication of the acquired immunodeficiency syndrome (AIDS) is AIDS dementia complex (ADC). The authors evaluated seven patients with AIDS (aged 28-55 years, all male) for ADC by psychiatric evaluation, neuropsychological testing, CT scanning, and IMP-SPECT. Six of seven patients exhibited cognitive or behavioral abnormalities. Neuropsychological testing showed general deficits but no cases of explicit dementia. SPECT showed marked abnormalities in two cases: posterior temporal-parietal diminution of tracer uptake in one case (posterior/anterior=0.81) and marked right/left subcortical asymmetry (1.17) in the other. In three additional cases there was asymmetric tracer uptake in the subcortical and parietal regions. CT findings were normal in all seven cases. The authors conclude that functional imaging with the use of IMP-SPECT may be a useful method to follow ADC progression and response to therapy

    To determine safety and efficacy of tumor necrosis factor (TNF) and interferon-gamma (IFN gamma) in the treatment of patients with acquired immunodeficiency syndrome (AIDS)-related complex, a randomized, double-blind study was conducted. Twenty-five patients with AIDS-related complex and CD4 lymphocytes less than or equal to 500 x 10(6)/L attended an AIDS Clinical Trials Unit of a tertiary referral center. Patients were administered tumor necrosis factor (TNF) (10 micrograms/m2) or IFN gamma (10 micrograms/m2), or both intramuscularly three times weekly for 16 weeks. Side effects from all three preparations included fever, constitutional symptoms, and local reactions. No significant hematologic, hepatic, renal, or coagulation abnormalities were observed. CD4 lymphocyte counts, beta 2-microglobulin, p24 antigen levels, and anti-p24 antibody did not change significantly during therapy. Similarly, no significant change was noted in rates of HIV isolation from peripheral blood mononuclear cells or plasma. TNF and IFN gamma were tolerable after premedication with acetaminophen; however, no significant change in markers of human immunodeficiency virus infection was demonstrated. These cytokines alone do not appear to be of benefit, nor do they appear to hasten the progression of HIV infection.

    Single photon emission computed tomography (SPECT) studies were performed in AIDS dementia complex using IMP in 12 patients (and HM-PAO in four of these same patients). In all patients, SPECT revealed either multiple or focal uptake defects, the latter corresponding with focal signs or symptoms in all but one case. Computerized tomography showed a diffuse cerebral atrophy in eight of 12 patients, magnetic resonance imaging exhibited changes like atrophy and/or leukoencephalopathy in two of five cases. Our data indicate that both disturbance of cerebral amine metabolism and alteration of local perfusion share in the pathogenesis of AIDS dementia complex. SPECT is an important aid in the diagnosis of AIDS dementia complex and contributes to the understanding of the pathophysiological mechanisms of this disorder

    HIV/AIDS have not only increased the health care burden especially in developing countries, it equally complicates the presentation of many diseases. Some well known disease entities now occur in fulminant complexities not previously described or known as such. The objective of this article is to report an unusual presentation of HIV/AIDS patients to the surgeon with Axillary and ipsilateral breast swelling. This is a report of three cases seen and managed by the authors. Three adult female patients presented with progressively increasing axillary and ipsilateral breast swellings. They also had associated fevers and weight loss. Their main concern had been development of breast cancer. One of the patients was a known retroviral positive on Highly Active Anti-Retroviral Therapy (HAART). Examination revealed axillary abscess and ipsilateral breast oedema in two cases. The patient on HAART had a hard breast-axillary mass complex. Biopsy (FNAB) revealed inflammatory cells and no malignancy in all three cases. HIV screening was positive in all cases. One of the patients had excision of breast-axillary mass complex, and the histology showed features of chronic inflammation, with no malignant cells. The other two had incision and drainage of their axillary abscess. This shows the ubiquitous presentation of HIV/AIDS in our environment and surgeons should be aware of the breast axillary complex in HIV/AIDS. Medical practitioners should be careful to obtain accurate diagnosis before embarking on treatment especially mutilating surgical procedures.

The current study was a qualitative focused ethnography aimed at exploring the complexities of care; working environments; and knowledge, skills, and efforts of care aides who work in nursing homes. Over the past decade, dramatic shifts in staffing patterns in Canadian nursing homes have transformed care aides' assistive and caring roles. Care aides are now the central and most accessible service providers to nursing home residents. In the current article, the authors (a) conceptualize care aide work as caring rather than caring activities, (b) explore relational care as a foundational and significant component of care aide work, (c) interpret care aides' relational care practices through the lens of Swanson's Middle Range Theory of Caring, and (d) describe how nursing home managers can empower care aides to do this work.

    While structures and reactivities of many small molecules can be computed efficiently and accurately using quantum chemical methods, heuristic approaches remain essential for modeling complex structures and large-scale chemical systems. Here, we present a heuristics-aided quantum chemical methodology applicable to complex chemical reaction networks such as those arising in cell metabolism and prebiotic chemistry. Chemical heuristics offer an expedient way of traversing high-dimensional reactive potential energy surfaces and are combined here with quantum chemical structure optimizations, which yield the structures and energies of the reaction intermediates and products. Application of heuristics-aided quantum chemical methodology to the formose reaction reproduces the experimentally observed reaction products, major reaction pathways, and autocatalytic cycles.

  16. Value assessment aid to complex decision making. Final report

    Humphress, G.; Lewis, E.

    1982-07-01

    Value assessment (VA) is a new decision aid that can improve the performance of decisionmakers confronted with multiple attributes and conflicting objectives. Managers who are not supported by formal decision aids turn to various ''satisficing'' or effort-reducing biases that can lead to serious errors in the decisionmaking process. Value assessment, on the other hand, is an optimizing approach to problem-solving behavior. VA helps decisionmakers overcome the tendency to turn to effort-reducing biases by reducing the complexity of making tradeoffs and weighing all available information. Many of the issues which confront modern electric utility managements are complex, multiple attribute problems which must be viewed from engineering, financial and socio-political perspectives simultaneously. Added to this are the complications contributed by factors like uncertainty, risk, incomplete information and conflicting objectives among the public it serves. This is the complex decisionmaking arena which VA is intended to support

    Gaudreault, Francis; Najmanovich, Rafael J

    2015-07-27

    Small-molecule protein docking is an essential tool in drug design and to understand molecular recognition. In the present work we introduce FlexAID, a small-molecule docking algorithm that accounts for target side-chain flexibility and utilizes a soft scoring function, i.e. one that is not highly dependent on specific geometric criteria, based on surface complementarity. The pairwise energy parameters were derived from a large dataset of true positive poses and negative decoys from the PDBbind database through an iterative process using Monte Carlo simulations. The prediction of binding poses is tested using the widely used Astex dataset as well as the HAP2 dataset, while performance in virtual screening is evaluated using a subset of the DUD dataset. We compare FlexAID to AutoDock Vina, FlexX, and rDock in an extensive number of scenarios to understand the strengths and limitations of the different programs as well as to reported results for Glide, GOLD, and DOCK6 where applicable. The most relevant among these scenarios is that of docking on flexible non-native-complex structures where as is the case in reality, the target conformation in the bound form is not known a priori. We demonstrate that FlexAID, unlike other programs, is robust against increasing structural variability. FlexAID obtains equivalent sampling success as GOLD and performs better than AutoDock Vina or FlexX in all scenarios against non-native-complex structures. FlexAID is better than rDock when there is at least one critical side-chain movement required upon ligand binding. In virtual screening, FlexAID results are lower on average than those of AutoDock Vina and rDock. The higher accuracy in flexible targets where critical movements are required, intuitive PyMOL-integrated graphical user interface and free source code as well as precompiled executables for Windows, Linux, and Mac OS make FlexAID a welcome addition to the arsenal of existing small-molecule protein docking methods.

    Transforming growth factor (TGF)-β inhibits hepatitis B virus (HBV) replication although the intracellular effectors involved are not determined. Here, we report that reduction of HBV transcripts by TGF-β is dependent on AID expression, which significantly decreases both HBV transcripts and viral DNA, resulting in inhibition of viral replication. Immunoprecipitation reveals that AID physically associates with viral P protein that binds to specific virus RNA sequence called epsilon. AID also binds to an RNA degradation complex (RNA exosome proteins), indicating that AID, RNA exosome, and P protein form an RNP complex. Suppression of HBV transcripts by TGF-β was abrogated by depletion of either AID or RNA exosome components, suggesting that AID and the RNA exosome involve in TGF-β mediated suppression of HBV RNA. Moreover, AID-mediated HBV reduction does not occur when P protein is disrupted or when viral transcription is inhibited. These results suggest that induced expression of AID by TGF-β causes recruitment of the RNA exosome to viral RNP complex and the RNA exosome degrades HBV RNA in a transcription-coupled manner.

    Sabherwal, Pooja; Singh, Latika; Agrawal, Monika

    2018-03-30

    In this paper, a novel algorithm for the accurate detection of QRS complex by combining the independent detection of R and S peaks, using fusion algorithm is proposed. R peak detection has been extensively studied and is being used to detect the QRS complex. Whereas, S peaks, which is also part of QRS complex can be independently detected to aid the detection of QRS complex. In this paper, we suggest a method to first estimate S peak from raw ECG signal and then use them to aid the detection of QRS complex. The amplitude of S peak in ECG signal is relatively weak than corresponding R peak, which is traditionally used for the detection of QRS complex, therefore, an appropriate digital filter is designed to enhance the S peaks. These enhanced S peaks are then detected by adaptive thresholding. The algorithm is validated on all the signals of MIT-BIH arrhythmia database and noise stress database taken from physionet.org. The algorithm performs reasonably well even for the signals highly corrupted by noise. The algorithm performance is confirmed by sensitivity and positive predictivity of 99.99% and the detection accuracy of 99.98% for QRS complex detection. The number of false positives and false negatives resulted while analysis has been drastically reduced to 80 and 42 against the 98 and 84 the best results reported so far.

    Non-electronic communication aids provide one form of augmentative and alternative communication (AAC) for people with complex communication needs. The aim here was to explore non-electronic communication aids as one AAC option and research challenges. This aim was addressed by reviewing funding for the provision of AAC systems, data from an Australian pilot project providing non-electronic communication aids, an audit of aided AAC published studies (2000-2009), and discussion of the review literature. Combined, these sources indicate that although there is great demand for non-electronic communication aids, funding schemes, both in Australia and internationally, have focused on electronic communication aids. Such funding has usually failed to meet the total device costs and has not provided for adequate speech-language pathology support. Data from the pilot indicated the demand for non-electronic communication aids, and patterns suggest potential factors that govern the types selected. Despite the high demand for non-electronic aids, the research literature has tended to focus on electronic communication aids, including within intervention studies and addressing design features and long-term outcomes. Concerns about ensuring that AAC systems are chosen according to the assessed needs of individuals are discussed within the context of limitations in outcomes research and appropriate outcome measures.

    This article is a systhematic literature review including the period from 1994 to 2009, whose objective was to discuss the aged woman's vulnerability in relation to Acquired Imunodeficiency Syndrome (Aids). The search for scientific texts was accomplished in the following databases: Biblioteca Virtual em Saúde, Scientific Eletronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE). The descriptors used were vulnerability, woman and Aids. Eighteen texts were analyzed, including articles in scientific journals, thesis and dissertations. As a conclusion, it was noted that aged women and vulnerability to Aids are directly related, through gender characteristics including submission and that were built historical and socially. We consider as fundamental the development of studies which may generate publications accessible to women, in order to help them see themselves as persons vulnerable to Aids contagion just for being women.

    2015-01-01

    Background Appropriate use of highly active antiretroviral therapy (HAART) can markedly decrease the risk of progression to acquired immunodeficiency syndrome (AIDS) and of premature mortality. We aimed to characterize the trends between 1981 and 2013 in AIDS-defining illnesses (ADIs) and in the number AIDS-related deaths in British Columbia (BC), Canada. Methods We included data of 3550 HIV-positive individuals, aged 19 years or older, from different administrative databases in BC. We estimated the relative risk of developing an ADI over time using a Negative Binomial model, and we investigated trends in the percentage of all deaths associated with AIDS using generalized additive models. Findings The number of ADIs has decreased dramatically to its lowest level in 2013. The peak of the AIDS epidemic in BC happened in 1994 with 696 ADIs being reported (rate 42 ADIs per 100 person-years). Since 1997, the number of ADIs decreased from 253 (rate 7 per 100 person-years) to 84 cases in 2013 (rate 1 per 100 person-years) (p-value equals to zero for the trend in the number of ADIs). We have also shown that out of 22 ADIs considered, only PCP maintained its prominent ranking (albeit with much reduced overall prevalence). Finally, we observed that over time very few deaths were related to AIDS-related causes, especially in the most recent years. Interpretation We showed that the number of new ADIs and AIDS-related mortality have been decreasing rapidly over time in BC. These results provide further evidence that integrated comprehensive free programs that facilitate testing, and deliver treatment and care to this population can be effective in markedly decreasing AIDS-related morbidity and mortality, thus suggesting that controlling and eventually ending AIDS is possible.

    2011-08-01

    An expanding body of literature explores the role of African church groups in facilitating or hindering the support of people living with AIDS and challenging or contributing to HIV/AIDS-related stigma. Treating church groups as social spaces in which HIV/AIDS-related stigma may potentially be challenged, we systematically review this literature, identifying five themes that highlight the complex and contradictory role of the church as a potential agent of health-enhancing social change. In many ways the church perpetuates HIV/AIDS-related stigma through (i) moralistic attitudes and (ii) its reinforcement of conservative gender ideologies. However some churches have managed move towards action that makes a more positive contribution to HIV/AIDS management through (iii) promoting various forms of social control for HIV prevention, (iv) contributing to the care and support of the AIDS-affected and (v) providing social spaces for challenging stigmatising ideas and practices. We conclude that church groups, including church leadership, can play a key role in facilitating or hindering the creation of supportive social spaces to challenge stigma. Much work remains to be done in developing deeper understandings of the multi-layered factors that enable some churches, but not others, to respond effectively to HIV/AIDS.

    Science.gov (United States)

    Jonsson, C; Soderholm, P

    1995-01-01

    This paper is concerned with the emergence of transnational cooperative structures in response to AIDS. Of chief concern are efforts to create and maintain links among and between intergovernmental organizations (IGO) in the UN system and the many heterogenous organizations usually included under the nongovernmental organization (NGO) label. After discussing the nature of the AIDS issue, the authors focus upon the various ways of framing the AIDS issue and the effort by the Global Program on AIDS to coordinate IGO and NGO activities. In closing, they identify lessons and insights of broader applicability emanating from the AIDS case. The paper discusses the nature of AIDS, AIDS as a medical problem, AIDS as a human rights problem, AIDS as a socioeconomic problem, forging IGO-NGO links, an international NGO forum, informal networking, NGOs and AIDS-related foreign assistance, representation, formal versus informal coordination, costs of network building, degree of organization, and expertise.

    Perry, S W; Markowitz, J

    1986-10-01

    Although the medical and psychosocial problems posed by acquired immune deficiency syndrome (AIDS) are unique, interventions to treat AIDS-related psychiatric disorders are currently available. The depression, delirium, and denial that occur in medically hospitalized patients with AIDS respond to standard psychotherapeutic and psychopharmacological approaches. Outpatients with AIDS or AIDS-related complex benefit from clarification, abreaction, and support if the therapist accepts the regression associated with the sick role, focuses initially on somatic rather than on psychological concerns, and overcomes unwarranted fears of contagion. Patients with AIDS-related dementia are helped considerably by early diagnosis and planning, and patients with antibodies to the AIDS virus require a psycho-educational approach that includes stress inoculation and problem-solving techniques. The authors describe the above interventions as well as common countertransference responses that impede their implementation.

    Common cause failure analysis, also called common mode failure analysis, is an integral part of a complete system reliability analysis. Existing methods of computer aided common cause failure analysis are extended by allowing analysis of the complex systems often encountered in practice.

  14. Mission improbable: Does petroleum-related aid address the resource curse?

    International Nuclear Information System (INIS)

    Kolstad, Ivar; Wiig, Arne; Williams, Aled

    2009-01-01

    Petroleum-related aid programmes and projects are a key part of donor activities in oil-rich developing countries. This paper critically assesses petroleum-related aid activities, using the Norwegian Oil for Development programme as a main case. Recent research suggests that institutions, or governance, are essential in averting a resource curse. While governance issues are beginning to receive more attention in these types of programmes, they still form a minor part of programme activities. The narrow sector focus that characterizes petroleum-related aid makes it unlikely that it will produce the higher order institutional changes needed to lift the resource curse. Petroleum-related aid activities address the issue of corruption only to a limited extent. Given the commercial and political interests of donor countries, questions about the integrity and credibility of these types of programmes can be raised

    The purpose of this quantitative study is to understand the global security perspective on the effects of executive cognitive function (ECF) on Complex Behavioral Screening Intervention and HIV/AIDS. The HIV/AIDS pandemic is as much a social, political, economic, and cultural problem as a biomedical one. HIV/AIDS is associated centrally with the collapse not just of communities and families but potentially of states, with some of the largest public health interventions ever and enormous questions about governance, a huge population of orphans, and deep questions about intergenerational relations and cultural transmission. This study also is to develop a screening instrument that improves quality of life for individuals with executive cognitive impairments and behavior problems in our communities and the global society.

    Full Text Available 50 years after the publication of the first and influential article in international relations (IR analyzing foreign aid motivations, A theory of foreign aid, by Hans Morgenthau, IR scholarship has not yet accomplished a consistent theoretical body explaining international development cooperation. Most of the empirical studies on foreign aid have been contributions from other disciplines, especially economics. Research from the field of international relations has been mostly descriptive or poorly connected with IR paradigms.This article proposes to analyze motivations of foreign aid allocations decisions of donors. These motivations will be examined from the theoretical perspective of the international relations scholarship. In this way, it is sought to contribute, from the discipline of IR, to the explanation of the process in which developed countries make transfers of resources to developing countries.

    Full Text Available The present work aims to reflect on the influence of HIV / AIDS on social relations, sexuality and adolescent affectivity. We conducted a literature review and subsequent theoretical discussion on the topic, with the methodology of qualitative analysis of texts and scientific articles. The findings of the study demonstrated that it is necessary to fully consider the various psychosocial aspects of this dynamic, since the psychological aspects significantly influence disease progression and quality of life of HIV patient. For adolescents, this influence becomes even greater, because puberty is a specific stage of biological development, emotional and social, where social interaction plays an important role for the construction of the subject's personality. It is hoped that this study may contribute to the reflection on the importance of creating themselves coping strategies and health care interventions geared to this particular group, especially with regard to the psychologist, who should seek to accommodate these demands subjects, contributing to a healthy psychosocial development, considering its specific features.

    The Sun article, "Employers finding that AIDS in the workplace is a managerial nightmare" (April 3), did not accurately portray the status of AIDS in the workplace. The AIDS virus, HTLV III, is transmitted by body fluids, primarily semen and blood, and there is no known risk of transmitting the virus by casual contact in the workplace. The Center for Disease Control (CDC) released guidelines for child care workers last August. Guidelines on preventing transmission of AIDS in the workplace were issued by CDC in November 1985. These guidelines specifically discussed health care, personal service, and food service workers. The recommendations were against routine screening. Furthermore, employment should not be restricted on the basis of a positive HTLV III antibody test. A person with HTLV III infection should be exempt from the workplace only if there are circumstances interfering with job performance. In Maryland, the Governor's Task Force on AIDS has gone on record as endorsing CDC guidelines related to employment. Furthermore, the task force condemns discrimination based on the disease AIDS, AIDS Related Complex (ARC), or HTLV III infection. Increasingly AIDS patients are being considered legally disabled and therefore are protected by federal and state laws prohibiting discrimination on the basis of a handicap. Marylanders who are subjected to mandatory HTLV III screening in the workplace, or if discriminated against on the basis of HTLV III inefction, should contact the Maryland Commission on Human Relations, the Maryland Department of Health and Mental Hygiene, or the Health Education Resource Organization (HERO). All 3 of these resources guarantee confidentiality. It is only by employees reporting incidents that a nightmare in the workplace can be avoided in Maryland. full text

    While the International Prognostic Index is commonly used to predict outcomes in immunocompetent patients with aggressive B-cell non-Hodgkin lymphomas, HIV-infection is an important competing risk for death in patients with AIDS-related lymphomas. We investigated whether a newly created prognostic score (AIDS-related lymphoma International Prognostic Index) could better assess risk of death in patients with AIDS-related lymphomas. We randomly divided a dataset of 487 patients newly diagnosed with AIDS-related lymphomas and treated with rituximab-containing chemoimmunotherapy into a training (n=244) and validation (n=243) set. We examined the association of HIV-related and other known risk factors with overall survival in both sets independently. We defined a new score (AIDS-related lymphoma International Prognostic Index) by assigning weights to each significant predictor [age-adjusted International Prognostic Index, extranodal sites, HIV-score (composed of CD4 count, viral load, and prior history of AIDS)] with three risk categories similar to the age-adjusted International Prognostic Index (low, intermediate and high risk). We compared the prognostic value for overall survival between AIDS-related lymphoma International Prognostic Index and age-adjusted International Prognostic Index in the validation set and found that the AIDS-related lymphoma International Prognostic Index performed significantly better in predicting risk of death than the age-adjusted International Prognostic Index (P=0.004) and better discriminated risk of death between each risk category (P=0.015 vs. P=0.13). Twenty-eight percent of patients were defined as low risk by the ARL-IPI and had an estimated 5-year overall survival (OS) of 78% (52% intermediate risk, 5-year OS 60%; 20% high risk, 5-year OS 50%).

    To analyze HIV/AIDS positive individual's perception and attitudes regarding dental services. One hundred and thirty-four subjects (30.0% of women and 70.0% of men) from Nuevo León, Mexico, took part in the study (2014). They filled out structured, analytical, self-administered, anonymous questionnaires. Besides the sociodemographic variables, the perception regarding public and private dental services and related professionals was evaluated, as well as the perceived stigma associated with HIV/AIDS, through a Likert-type scale. The statistical evaluation included a factorial and a non-hierarchical cluster analysis. Social inequalities were found regarding the search for public and private dental professionals and services. Most subjects reported omitting their HIV serodiagnosis and agreed that dentists must be trained and qualified to treat patients with HIV/AIDS. The factorial analysis revealed two elements: experiences of stigma and discrimination in dental appointments and feelings of concern regarding the attitudes of professionals or their teams concerning patients' HIV serodiagnosis. The cluster analysis identified three groups: users who have not experienced stigma or discrimination (85.0%); the ones who have not had those experiences, but feel somewhat concerned (12.7%); and the ones who underwent stigma and discrimination and feel concerned (2.3%). We observed a low percentage of stigma and discrimination in dental appointments; however, most HIV/AIDS patients do not reveal their serodiagnosis to dentists out of fear of being rejected. Such fact implies a workplace hazard to dental professionals, but especially to the very own health of HIV/AIDS patients, as dentists will not be able to provide them a proper clinical and pharmaceutical treatment.

    Full Text Available Abstract Background Individuals who are aware of the risk of infection and perceive themselves to be at risk of infection are more likely to take action to prevent HIV infection. The aim of this study was to assess the knowledge of HIV/AIDS among Iraqi women. Methods A secondary analysis of the 2000 Multiple Cluster Indicator Survey (MICS for Iraq was carried out to assess the extent of HIV/AIDS-related knowledge among Iraqi women. Results The majority of the 22,997 respondents were age 15–24 years (44.3%, currently married (51.4%, and resided in urban areas (71.7%. About 1 in 4 (26.0% of the study participants had no formal education. Only 49.9% had heard of HIV/AIDS. Overall, 60.5% did not know that HIV can be transmitted through blood transfusion. Meanwhile, 98.5% of the respondents did not know that HIV can be transmitted from mother to child through breast milk. Only 0.7% of the respondents reported that HIV cannot be transmitted through mosquito bites. The proportion of the respondents who had adequate knowledge on HIV/AIDS was 9.8%. Adequate knowledge of HIV/AIDS was negatively associated with being married, poor, having low education, and residing in rural areas. Conclusion Findings from this study indicate that adequate knowledge of HIV/AIDS among Iraqi is very limited and associated with marital status, education, wealth, and place of residence. This information may be of use in the design, targeting, monitoring and evaluation of programs aimed at improving HIV and AIDS related knowledge in Iraq.

    The epidemic of acquired immunodeficiency syndrome (AIDS) increased the incidence of lymphoma, particularly the non-Hodgkin's lymphoma. The lymphoma in immune deficient patients is usually high-grade, very aggressive and with poor prognostic. We report the radiologic characteristics of AIDS-related lymphoma in 19 patients and correlate with the literature. The disease was predominant in homosexual male patients, with mean age of 38 years. The radiological characteristics are nonspecific to differential diagnosis, but we must suspect of lymphoma. We found ring-enhanced lesions in the radiologic studies of central nervous system. Hylar and mediastinal lymphadenopath, nodules and alveolar infiltration were detected on thoracic examinations. Abdominal examinations showed hepatosplenomegaly, lymphadenopathy, hepatic focal lesions and thickneded with distorted mucosa in the alimentary tract. Bone involvement presented as focal and disseminated destructive lesions. (author)

  6. Diagnosis and Management of AIDS-related Diarrhea

    Directory of Open Access Journals (Sweden)

    John F Johanson

    1996-01-01

    Full Text Available The spectrum of illness associated with the acquired immunodeficiency syndrome (AIDS has been increasing since the initial description in 1981. While virtually all organ systems may be affected, the gastrointestinal tract appears to be a major target. Diarrhea is the most common symptom, affecting up to half of all AIDS patients during the course of their disease. Although diarrhea occurs frequently, its optimal management remains controversial. An extensive evaluation including stool studies and endoscopic biopsies of both the colon and small intestine has been widely recommended to identify all potential pathogenic organisms. An alternative approach is a more limited evaluation consisting of stool and blood cultures followed by symptomatic treatment with antidiarrheal agents if no specific organisms are identified. The clinical presentation of the most common opportunistic pathogens are reviewed, including several recently discovered organisms. Recommendations for treatment are followed by a brief discussion of management strategies used to care for patients with AIDS-related diarrhea.

  7. The development and application of composite complexity models and a relative complexity metric in a software maintenance environment

    Hops, J. M.; Sherif, J. S.

    1994-01-01

    A great deal of effort is now being devoted to the study, analysis, prediction, and minimization of software maintenance expected cost, long before software is delivered to users or customers. It has been estimated that, on the average, the effort spent on software maintenance is as costly as the effort spent on all other software costs. Software design methods should be the starting point to aid in alleviating the problems of software maintenance complexity and high costs. Two aspects of maintenance deserve attention: (1) protocols for locating and rectifying defects, and for ensuring that noe new defects are introduced in the development phase of the software process; and (2) protocols for modification, enhancement, and upgrading. This article focuses primarily on the second aspect, the development of protocols to help increase the quality and reduce the costs associated with modifications, enhancements, and upgrades of existing software. This study developed parsimonious models and a relative complexity metric for complexity measurement of software that were used to rank the modules in the system relative to one another. Some success was achieved in using the models and the relative metric to identify maintenance-prone modules.

  11. Algorithmic Relative Complexity

    2011-04-01

    Full Text Available Information content and compression are tightly related concepts that can be addressed through both classical and algorithmic information theories, on the basis of Shannon entropy and Kolmogorov complexity, respectively. The definition of several entities in Kolmogorov’s framework relies upon ideas from classical information theory, and these two approaches share many common traits. In this work, we expand the relations between these two frameworks by introducing algorithmic cross-complexity and relative complexity, counterparts of the cross-entropy and relative entropy (or Kullback-Leibler divergence found in Shannon’s framework. We define the cross-complexity of an object x with respect to another object y as the amount of computational resources needed to specify x in terms of y, and the complexity of x related to y as the compression power which is lost when adopting such a description for x, compared to the shortest representation of x. Properties of analogous quantities in classical information theory hold for these new concepts. As these notions are incomputable, a suitable approximation based upon data compression is derived to enable the application to real data, yielding a divergence measure applicable to any pair of strings. Example applications are outlined, involving authorship attribution and satellite image classification, as well as a comparison to similar established techniques.

    Full Text Available Objective: To assess the perceived HIV/AIDS related stigma a comprehensive and well developed stigma instrument is necessary. This study aimed to assess validity and reliability of the Persian version of HIV/AIDS related stigma scale which was developed by Kang et al for people living with HIV/AIDS in Iran.Materials and methods: Thescale was forward translatedby two bilingual academic members then both translations were discussed by expert team. Back-translation was done by two other bilingual translators then we carried out discussion with both of them. To evaluate understandability the scale was administered to 10 Persons Living with HIV/AIDS (PLWHA. Final Persian version was administered to 80 PLWHA in Qom, Iran in 2014. Test–retest reliability was assessed in a sample of 20 PLWHA after a week by intra-class correlation coefficient (ICC.Results: Cronbach’s alpha coefficient for overall scale was 0.85. Also Cronbach’s alpha coefficients for the five subscales were as follows: social rejection (9 items, α = 0.84, negative self-worth (4 items, α = 0.70, perceived interpersonal insecurity (2 items, α = 0.57, financial insecurity (3 items, α = 0.70, discretionary disclosure (2 items, α = 0.83. Test–retest reliability was also approved with ICC = 0.78. Correlation between items and their hypothesized subscale is greater than 0.5. Correlation between an item and its own subscale was significantly higher than its correlation with other subscales.Conclusion: This study demonstrate that the Persian version of HIV/AIDS related stigma scale is valid and reliable to assess HIV/AIDS related stigma perceived by people living whit HIV/AIDS in Iran.

  14. Accounts from the field: a public relations perspective on global AIDS/HIV.

    Bardhan, Nilanjana R

    2002-01-01

    This study is a theoretical as well as empirical exploration of the power and cultural differentials that mark and construct various intersecting discourses, specifically media discourse, on global AIDS/HIV. It applies the language and concepts of public relations to understand how the press coverage of the pandemic is associated with the variables that impact the newsmaking process as well as the public and policy implications of macro news frames generated over time. Theoretical work in the areas of agenda setting and news framing also instruct the conceptual framework of this analysis. Narrative analysis is used as a methodology to qualitatively analyze three pools of accounts-from people either living with AIDS/HIV, involved in AIDS/HIV work, or discursively engaged in the media construction of the pandemic; from transnational wire service journalists who cover the issue at global and regional levels; and policy shapers and communicators who are active at the global level. These three communities of respondents represent important stakeholders in the AIDS/HIV issue. The findings are analyzed from a public relations standpoint. Perhaps the most important finding of this study is that the public relations approaches used to address AIDS/HIV related issues need to be grounded in context-specific research and communicative practices that bring out the lived realities of AIDS/HIV at grassroots levels. The findings also posit that those situated at critical junctions between various stakeholders need to cultivate a finely balanced understanding of the etic and emic intersections and subjectivities of global/local AIDS/HIV.

  16. Securitizing HIV/AIDS: a game changer in state-societal relations in China?

    Science.gov (United States)

    Lo, Catherine Yuk-Ping

    2018-05-16

    China has experienced unprecedented economic growth since the 1980s. Despite this impressive economic development, this growth exists side by side with the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and severe acute respiratory syndrome (SARS) crises and the persisting deficiencies in public health provision in China. Acknowledging the prevailing health problems, the Chinese government has encouraged the development of health non-governmental organizations (NGOs) to respond to the health challenges and address the gaps in public health provision of the government. HIV/AIDS-focused NGOs have been perceived as the most outstanding civil society group developed in China. Considering the low priority of health policies since the economic reform, the limitation of the "third sector" activity permitted in authoritarian China, together with the political sensitivity of the HIV/AIDS problem in the country, this article aims to explain the proliferation of HIV/AIDS-focused NGOs in China with the usage of the securitization framework in the field of international relations (IR). The research that underpins this article is based on a desk-based literature review as well as in-depth field interviews with individuals working in HIV/AIDS-focused NGOs in China. Face-to-face interviews for this research were conducted between January and May in 2011, and between December 2016 and January 2017, in China. Discourse analysis was in particular employed in the study of the security-threat framing process (securitization) of HIV/AIDS in China. This article argues that the proliferation of HIV/AIDS-related NGOs in China is largely attributed to the normative and technical effects of HIV/AIDS securitization ushered in by the United Nations Security Council (UNSC) and supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria (hereinafter Global Fund) observed in China. Despite depicting a positive scenario, the development of HIV/AIDS

    2002-03-01

    Findings on knowledge, attitudes and beliefs related to HIV/AIDS among 520 Malaysian adolescents, aged 15 to 21 years, based on a survey conducted in Peninsular Malaysia showed that the average score for knowledge on HIV/AIDS was high, and majority showed a positive attitude towards the disease. However, misconceptions regarding transmission and gender bias related to sexual behaviour and contracting the disease prevailed. Although 72 percent of the sexually-experienced did not use protection at first sexual intercourse, 80 percent did not perceive themselves to be at risk of contracting HIV/AIDS. A critical review of existing HIV/AIDS prevention programmes to focus on adolescent risk-taking behaviour and sexuality issues, including male-female negotiation skills, is warranted.

    Beatriz Grinsztejn

    Full Text Available INTRODUCTION: We describe temporal trends in the mortality rates and factors associated with AIDS and non-AIDS related mortality at the Evandro Chagas Clinical Research Institute (IPEC, Oswaldo Cruz Foundation (FIOCRUZ. METHODS: Adult patients enrolling from 1986 through 2009 with a minimum follow up of 60 days were included. Vital status was exhaustively checked using patients' medical charts, through active contact with individuals and family members and by linkage with the Rio de Janeiro Mortality database using a previously validated algorithm. The CoDe protocol was used to establish the cause of death. Extended Cox proportional hazards models were used for multivariate modeling. RESULTS: A total of 3530 individuals met the inclusion criteria, out of which 868 (24.6% deceased; median follow up per patient was 3.9 years (interquartile range 1.7-9.2 years. The dramatic decrease in the overall mortality rates was driven by AIDS-related causes that decreased from 9.19 deaths/100PYs n 1986-1991 to 1.35/100PYs in 2007-2009. Non-AIDS related mortality rates remained stable overtime, at around 1 death/100PYs. Immunodeficiency significantly increased the hazard of both AIDS-related and non-AIDS-related causes of death, while HAART use was strongly associated with a lower hazard of death from either cause. CONCLUSIONS: Our results confirm the remarkable decrease in AIDS-related mortality as the HIV epidemic evolved and alerts to the conditions not traditionally related to HIV/AIDS which are now becoming more frequent, needing careful monitoring.

    Objective: To analyze the survival time of HIV/AIDS cases and related factors in Beijing from 1995 to 2015. Methods: A retrospective cohort study was conducted to analyze the data of 12 874 HIV/AIDS cases. The data were collected from Chinese HIV/AIDS Comprehensive Information Management System. Life table method was applied to calculate the survival proportion, and Cox proportion hazard regression model were used to identify the factors related with survival time. Results: Among 12 874 HIV/AIDS cases, 303 (2.4%) died of AIDS related diseases; 9 346 (72.6%) received antiretroviral therapy. The average survival time was 226.5 months (95 %CI : 223.0-230.1), and the survival rates of 1, 5, 10, and 15 years were 98.2%, 96.4%, 93.2%, and 91.9% respectively. Multivariate Cox proportion hazard regression model showed that AIDS phase ( HR =1.439, 95 %CI : 1.041-1.989), heterosexual transmission ( HR =1.646, 95 %CI : 1.184-2.289), being married ( HR =2.186, 95 %CI : 1.510-3.164); older age (≥60 years) at diagnosis ( HR =6.608, 95 %CI : 3.546-12.316); lower CD(4)(+)T cell counts at diagnosis (<350 cells/μl) ( HR =8.711, 95 %CI : 5.757-13.181); receiving no antiretroviral therapy (ART) ( HR =18.223, 95 %CI : 13.317-24.937) were the high risk factors influencing the survival of AIDS patients compared with HIV phase, homosexual transmission, being unmarried, younger age (≤30 years), higher CD(4)(+)T cell count (≥350 cell/μl) and receiving ART. Conclusion: The average survival time of HIV/AIDS cases was 226.5 months after diagnoses. Receiving ART, higher CD(4)(+)T cell counts at the first test, HIV phase, younger age, being unmarried and the homosexual transmission were related to the longer survival time of HIV/AIDS cases. Receiving no ART, the lower CD(4)(+)T cell counts at the first test, AIDS phase, older age, being married and heterosexual transmission indicated higher risk of death due to AIDS.

    HIV/AIDS and Ebola Virus Disease (EVD) are contemporary epidemics associated with significant social stigma in which communities affected suffer from social rejection, violence, and diminished quality of life. To compare and contrast stigma related to HIV/AIDS and EVD, and strategically think how lessons learned from HIV stigma can be applied to the current EVD epidemic. To identify relevant articles about HIV/AIDS and EVD-related stigma, we conducted an extensive literature review using multiple search engines. PubMed was used to search for relevant peer-reviewed journal articles and Google for online sources. We also consulted the websites of the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and the National Institutes of Health to retrieve up-to-date information about EVD and HIV/AIDS. Many stigmatizing attitudes and behaviors directed towards those with EVD are strikingly similar to those with HIV/AIDS but there are significant differences worthy of discussion. Both diseases are life-threatening and there is no medical cure. Additionally misinformation about affected groups and modes of transmission runs rampant. Unlike in persons with EVD, historically criminalized and marginalized populations carry a disproportionately higher risk for HIV infection. Moreover, mortality due to EVD occurs within a shorter time span as compared to HIV/AIDS. Stigma disrupts quality of life, whether it is associated with HIV infection or EVD. When addressing EVD, we must think beyond the immediate clinical therapeutic response, to possible HIV implications of serum treatment. There are emerging social concerns of stigma associated with EVD infection and double stigma associated with EVD and HIV infection. Drawing upon lessons learned from HIV, we must work to empower and mobilize prominent members of the community, those who recovered from the disease, and organizations working at the grassroots level to disseminate clear and accurate

    OBJECTIVE--To describe a nosocomial outbreak of cryptosporidiosis during four months after June 1989. SETTING--A department of infectious diseases in Copenhagen, seeing about half the patients with AIDS in Denmark. SUBJECTS--73 HIV antibody negative subjects and 60 antibody positive subjects...... admitted as inpatients during the transmission period of the outbreak (20 June-14 August), of whom 18 (17 with AIDS, one with AIDS related complex), developed cryptosporidiosis. Two further HIV negative subjects (one departmental secretary, one visiting relative) developed cryptosporidiosis. MAIN OUTCOME...... out ice for cold drinks. The mean incubation time was at least 13 days-that is, twice that in HIV-negative patients. Of the 18 patients with AIDS who developed cryptosporidiosis, five recovered, two were symptomless carriers, three died of unrelated causes, and eight died after prolonged diarrhoea...

    People living with HIV/AIDS are stigmatized. Although personal and social consequences of this stigmatization have been documented, research regarding its impact on social interactions is scarce. Latinos, and Puerto Ricans in particular, have voiced concern regarding AIDS stigma. The authors investigated the key role of social interaction in the process of stigmatization through in-depth, semistructured interviews in a sample of 30 Puerto Ricans living with HIV/AIDS. Participants reported instances in which AIDS stigma negatively influenced social interactions with family, friends, sexual partners, coworkers, and health professionals. Some of the consequences they described were loss of social support, persecution, isolation, job loss, and problems accessing health services. Findings support the need for interventions to address AIDS stigma and its consequences.

    Primary central nervous system lymphoma (PCNSL) is a frequent complication in acquired immunodeficiency syndrome (AIDS). The objective of this survey was to investigate incidence, clinical features, radiological findings, histologic diagnosis, treatment and outcome for all patients with histologically verified AIDS-related PCNSL diagnosed in Norway in 1989–2003. We identified the patients by chart review of all cases recorded as PCNSL in The Norwegian Cancer Registry (by law recording all cases of cancer in Norway) and all cases recorded as AIDS-related PCNSL in the autopsy registry at a hospital having 67% autopsy rate and treating 59% of AIDS patients in Norway, from 1989 to 2003. Histologic material and radiological images were reviewed. We used person-time techniques to calculate incidence rates of PCNSL among AIDS patients based on recordings on AIDS at the Norwegian Surveillance System for Communicable Diseases (by law recording all cases of AIDS in Norway). Twenty-nine patients had histologically confirmed, newly diagnosed AIDS-related PCNSL in Norway from 1989–2003. Only 2 patients had this diagnosis established while alive. AIDS patients had 5.5% lifetime risk of PCNSL. Their absolute incidence rate of PCNSL per 100 person-years was 1.7 (95%CI: 1.1–2.4) and decreased during the consecutive 5-year periods from 3.6, to 2.5, and to 0.4 (p < 0.001). Median survival from initial symptom of PCNSL was 2.3 months, but one patient was still alive 4 years after completed radiotherapy. This is the first national survey to confirm decreasing incidence of AIDS-related PCNSL. Despite dismal survival in most patients, the possibility of long term survival should prompt more aggressive diagnostics in suspected PCNSL

  9. The dynamics of the production of AIDS-related stigma among pregnant women living with HIV/AIDS in Rio de Janeiro, Brazil

    Directory of Open Access Journals (Sweden)

    Simone Monteiro

    Full Text Available The study analyses the relationship between AIDS-related stigma and the processes of discrimination prior to diagnosis among pregnant women living with HIV/AIDS. The fieldwork involved interviews about the life trajectories of 29 pregnant women living with HIV/AIDS, recruited at two AIDS services in Rio de Janeiro, Brazil. The analysis revealed that before HIV diagnosis, social and gender inequalities experienced by these women reduced their access to material and symbolic goods that could have enhanced educational and career prospects and their ability and autonomy to exercise sexual and reproductive rights. Being diagnosed with HIV triggered fear of moral judgment and of breakdown in social and family support networks. Given these fears, pregnant women living with HIV/AIDS opt for concealment of the diagnosis. It is necessary for health services, NGOs and government agencies to work together to face the factors that fuel stigma, such as socioeconomic and gender inequalities, taboos and prejudices related to sexuality, and also develop actions to enable women to redefine the meaning of the disease.

    The prevalence of acquired immunodeficiency syndrome (AIDS)-related lymphoma (ARL) is increasing in South Korea. The aim of this study is to identify the clinical features of ARL in South Korea. From 1998 through 2006, we retrospectively analysed a total of 23 cases of ARL from seven institutions. The patients consisted of 20 males and 3 females at a median age of 40 (range, 20-72) on diagnosis of AIDS. ARL developed at their median age of 41 (range, 24-72). The histological diagnosis was aggressive B cell lymphoma in the majority, but rare T cell and NK/T cell lymphoma were also included. Ten of 23 (43.5%) was receiving highly active anti-retroviral therapy (HAART) before the diagnosis of ARL. Fifteen of twenty-three patients were given combination chemotherapy with/without radiation, four were given radiation alone, and four did not receive any treatment against medical advice. Of 20 patients followed-up, nine were alive in remission, two alive in disease, one died of treatment related complication, four died of progressive lymphoma, four died of AIDS related causes. The response to treatment included complete response (CR) in eight (44.4%), partial response (PR) in four (22.2%) and progressive disease (PD) in three (16.7%). The response to HARRT was evaluable in 13 patients based on CD4+ cell count and human immnodeficiency virus (HIV) viral load, among which nine (69.2%) responded. Estimated median survival time was 43.9 months. Although the population of patients is small, this is the first clinical data analyses of Korean ARL patients. As a substantial portion of the patients remains alive disease free, the impact of HAART on the clinical course of ARL needs further follow-up and evaluation. (author)

    Background Few data exist on how the HIV/AIDS epidemic may influence population mental health. The associations were examined between knowing someone who died of HIV/AIDS and common mental disorders among South African adults. Methods Between 2002 and 2004, a nationally representative sample of 4351 adults were interviewed about personally knowing someone who died of HIV/AIDS, and the World Health Organization Composite International Diagnostic Interview was used to generate psychiatric diagnoses for depression, anxiety and substance abuse disorders during the preceding 12 months based on the Diagnostic and Statistical Manual, 4th edition (DSM-IV). Results Overall, 42.2% of the sample knew someone who died of HIV/AIDS, and 16.5% met the criteria for at least one DSM-IV diagnosis. Individuals who knew someone who died of HIV/AIDS were significantly more likely to have any DSM-IV defined disorder, including any depressive, anxiety or substance-related disorder (pdrug dependence or abuse. Based on these results, it is estimated that up to 15% of 12-month DSM-IV disorders in the South African adult population may be related to knowing someone who died of HIV/AIDS. Conclusion These novel data suggest that AIDS-related mortality may contribute substantially to the burden of mental disorders in settings of high HIV prevalence. While this finding requires further investigation, these data suggest the need to strengthen mental health services in communities where HIV/AIDS is prevalent. PMID:19074926

  12. Primary effect of chemotherapy on the transcription profile of AIDS-related Kaposi's sarcoma

    Drugs & used in anticancer chemotherapy have severe effects upon the cellular transcription and replication machinery. From in vitro studies it has become clear that these drugs can affect specific genes, as well as have an effect upon the total transcriptome. Total mRNA from two skin lesions from a single AIDS-KS patient was analyzed with the SAGE (Serial Analysis of Gene Expression) technique to assess changes in the transcriptome induced by chemotherapy. SAGE libraries were constructed from material obtained 24 (KS-24) and 48 (KS-48) hrs after combination therapy with bleomycin, doxorubicin and vincristine. KS-24 and KS-48 were compared to SAGE libraries of untreated AIDS-KS, and to libraries generated from normal skin and from isolated CD4+ T-cells, using the programs USAGE and HTM. SAGE libraries were also compared with the SAGEmap database. In order to assess the primary response of AIDS-related Kaposi's sarcoma (AIDS-KS) to chemotherapy in vivo, we analyzed the transcriptome of AIDS-KS skin lesions from a HIV-1 seropositive patient at two time points after therapy. The mRNA profile was found to have changed dramatically within 24 hours after drug treatment. There was an almost complete absence of transcripts highly expressed in AIDS-KS, probably due to a transcription block. Analysis of KS-24 suggested that mRNA pool used in its construction originated from poly(A) binding protein (PABP) mRNP complexes, which are probably located in nuclear structures known as interchromatin granule clusters (IGCs). IGCs are known to fuse after transcription inhibition, probably affecting poly(A)+RNA distribution. Forty-eight hours after chemotherapy, mRNA isolated from the lesion was largely derived from infiltrating lymphocytes, confirming the transcriptional block in the AIDS-KS tissue. These in vivo findings indicate that the effect of anti-cancer drugs is likely to be more global than up- or downregulation of specific genes, at least in this single patient with

    Kaposi's Sarcoma (KS) is a proliferation of aberrant vascular structures lined by spindle cells, and is caused by a gammaherpes virus (HHV8/KSHV). Its course is aggravated by co-infection with HIV-1, where the timing of infection with HIV-1 and HHV8 is important for the clinical outcome. In order to better understand the pathogenesis of KS, we have analysed tissue from two AIDS-KS lesions, and from normal skin by serial analysis of gene expression (SAGE). Semi-quantitative RT-PCR was then used to validate the results. The expression profile of AIDS-related KS (AIDS-KS) reflects an active process in the skin. Transcripts of HHV8 were found to be very low, and HIV-1 mRNA was not detected by SAGE, although it could be found using RT-PCR. Comparing the expression profile of AIDS-KS tissue with publicly available SAGE libraries suggested that AIDS-KS mRNA levels are most similar to those in an artificially mixed library of endothelial cells and leukocytes, in line with the description of KS lesions as containing spindle cells with endothelial characteristics, and an inflammatory infiltrate. At least 64 transcripts were found to be significantly elevated, and 28 were statistically downregulated in AIDS-KS compared to normal skin. Five of the upregulated mRNAs, including Tie 1 and sialoadhesin/CD169, were confirmed by semi-quantitative PCR to be elevated in additional AIDS-KS biopsies. Antibodies to sialoadhesin/CD169, a known marker of activated macrophages, were shown to specifically label tumour macrophages. The expression profile of AIDS-KS showed 64 genes to be significantly upregulated, and 28 genes downregulated, compared with normal skin. One of the genes with increased expression was sialoadhesin (CD169). Antibodies to sialoadhesin/CD169 specifically labelled tumour-associated macrophages, suggesting that macrophages present in AIDS-KS lesions belong to a subset of human CD169+ macrophages

    The aim of this study was to evaluate the levels of knowledge of pre-school teachers working in the province center of Isparta related with basic first-aid practices and some factors which affected these levels of knowledge. In this cross-sectional, analytic study, 110 pre-school teachers working in the province center of Isparta constituted the population. A questionnaire questioning sociodemographic properties and the level of knowledge related with first-aid practices was applied under supervision. The level of knowledge was evaluated on a 20-point scale. In the analyses, Kruskal-Wallis and Mann-Whitney U tests and Spearman's rank correlation were used. The study was approved by the Ethical Committee for Clinical Studies of Süleyman Demirel University School of Medicine (registration number: 105). The mean score of first-aid knowledge of the pre-school teachers was found to be 11.9±2.9. The least known issues included washing the wound by soap and water after a dog bite, information related with the necessity of immobilization of a child who has fallen from a high level and the phone number of National Poison Information Center (16.4%, 20.9% and 22.7%, respectively). The scores of the subjects whose knowledge of first-aid was evaluated to be well were higher compared to the subjects whose knowledge of first-aid was evaluated to be moderate (p=0.009) and poor (p=0.001). It was found that first-aid scores did not show significant difference in terms of age, working period, having received first-aid training and having faced with a condition requiring first-aid previously (p>0.05, for all comparisons). It was found that pre-school teachers had insufficient first-aid knowledge. Since the first-aid knowledge scores of the subjects who reported that they received first-aid training before did not show significant difference, it was thought that the quality of training was as important as receiving training.

    Full Text Available Neurologic complications of human immunodeficiency virus (HIV infection and acquired immune deficiency syndrome (AIDS frequently lead to disability or death in affected patients. The aim of this study was to determine whether survival patterns differ between men and women with HIV/AIDS-related neurologic disease (neuro-AIDS.Retrospective cohort data from a statewide surveillance database for HIV/AIDS were used to characterize survival following an HIV/AIDS-related neurologic diagnosis for men and women with one or more of the following conditions: cryptococcosis, toxoplasmosis, primary central nervous system lymphoma, progressive multifocal leukoencephalopathy, and HIV-associated dementia. A second, non-independent cohort was formed using university-based cases to confirm and extend the findings from the statewide data. Kaplan-Meier analysis was used to compare the survival experiences for men and women in the cohorts. Cox regression was employed to characterize survival while controlling for potential confounders in the study population.Women (n=27 had significantly poorer outcomes than men (n=198 in the statewide cohort (adjusted hazard ratio=2.31, 95% CI: 1.22 to 4.35, and a similar, non-significant trend was observed among university-based cases (n=17 women, 154 men. Secondary analyses suggested that this difference persisted over the course of the AIDS epidemic and was not attributable to differential antiretroviral therapy responses among men and women.The survival disadvantage of women compared to men should be confirmed and the mechanisms underlying this disparity elucidated. If this relationship is confirmed, targeted clinical and public health efforts might be directed towards screening, treatment, and support for women affected by neuro-AIDS.

    Background HIV/AIDS remain a major public health concern in Nigeria. People living with HIV/AIDS (PLWHA) face not only personal medical problems but also social problems associated with the disease such as stigma and discriminatory attitudes. This study provides an insight into HIV/AIDS related stigma and discrimination against PLWHA in Nigeria. Methods The data for this study was extracted from the 2013 Nigeria Demographic and Health Survey conducted by the National Population Commission. All men and women aged 15–49 years, permanent residents and visitors of the households were eligible for the interview. Several questionnaires were used in the survey, some covering questions on HIV/AIDS. Results A total of 56 307 men and women aged 15–49 years participated in this national survey. About half of the population in Nigeria have HIV stigma. Younger persons, men, those without formal education and those within poor wealth index are more likely to have stigma towards PLWHA. In addition, married people are more likely to have stigma on PLWHA and are more likely to blame PLWHA for bringing the disease to the community. Also about half of the population discriminates against PLWHA. However, those with higher levels of education and those from higher wealth index seem to be more compassionate towards PLWHA. About 70% in the population are willing to care for relative with AIDS, even more so among those with higher level of education. Conclusion There is a high level of HIV stigma and discrimination against PLWHA in the Nigerian population. Education seems to play a major role in the society with respect to HIV stigma and discrimination against PLWHA. Educating the population with factual information on HIV/AIDS is needed to reduce stigma and discrimination towards PLWHA in the community. PMID:26658767

  2. Complex manifolds in relativity

    Flaherty, E.J. Jr.

    1975-01-01

    Complex manifold theory is applied to the study of certain problems in general relativity. The first half of the work is devoted to the mathematical theory of complex manifold. Then a brief review of general relativity is given. It is shown that any spacetime admits locally an almost Hermitian structure, suitably modified to be compatible with the indefinite metric of spacetime. This structure is integrable if and only if the spacetime admits two geodesic and shearfree null congruences, thus in particular if the spacetime is type D vacuum or electrified. The structure is ''half-integrable'' in a suitable sense if and only if the spacetime admits one geodesic and shearfree null congruence, thus in particular for all algebraically special vacuum spacetimes. Conditions for the modified Hermitian spacetime to be Kahlerian are presented. The most general metric for such a modified Kahlerian spacetime is found. It is shown that the type D vacuum and electrified spacetimes are conformally related to modified Kahlerian spacetimes by a generally complex conformal factor. These latter are shown to possess a very rich structure, including the existence of Killing tensors and Killing vectors. A new ''explanation'' of Newman's complex coordinate transformations is given. It is felt to be superior to previous ''explanations'' on several counts. For example, a physical interpretation in terms of a symmetry group is given. The existence of new complex coordinate transformations is established: Nt is shown that any type D vacuum spacetime is obtainable from either Schwarzschild spacetime or ''C'' spacetime by a complex coordinate transformation. Finally, some related topics are discussed and areas for future work are outlined. (Diss. Abstr. Int., B)

    Cotton fibers are an excellent model for understanding of cellulose biosynthesis in higher plants. In this study, we determined a high cellulose biosynthesis activity in vitro by optimizing biochemical reaction conditions in cotton fibers. By adding a commercial cellulase enzyme into fibers extraction process, we extracted markedly higher levels of GhCESA1 and GhCESA8 proteins and observed an increase in β-1,4-glucan and β-1,3-glucan products in vitro. LC-MS/MS analysis of anti-GhCESA8-immunoprecipitated proteins showed that 19 proteins could be found in three independent experiments including four CESAs (GhCESA1,2,7,8), five well-known non-CESA proteins, one callose synthase (CALS) and nine novel proteins. Notably, upon the cellulase treatment, four CESAs, one CALS and four novel proteins were measured at relatively higher levels by calculating total peptide counts and distinct peptide numbers, indicating that the cellulase-aid-extracted proteins most likely contribute to the increase in β-glucan products in vitro. These results suggest that the cellulase treatment may aid to release active cellulose synthases complexes from growing glucan chains and make them more amenable to extraction. To our knowledge, it is the first time report about the functional identification of the potential proteins that were associated with plant cellulose and callose synthases complexes by using the cellulase-aided protein extraction.

    Drawing on the Greater Involvement of People with HIV/AIDS (GIPA) principle, the HIV/AIDS movement began to "democratize" research in Canada in the mid-1990s. To date, there is little evidence about the success of the community-based research (CBR) movement in relation to the implementation of GIPA. We draw on findings from a larger study examining barriers and facilitating factors in relation to HIV-related CBR in Ontario, Canada. An online survey was completed by 39 senior managers in Ontario AIDS service organizations (ASOs). Twenty-five in-depth, semi-structured interviews were then conducted to further explore the survey findings. Survey respondents reported that, compared to researchers and frontline service providers, people living with HIV/AIDS (PLWHA) tended to be the least involved in all stages (input, process and outcome) of CBR projects. AIDS service organizations with a mandate that included serving rural and urban communities reported even lower levels of PLWHA involvement in CBR. Qualitative data reveal complex barriers that make meaningful PLWHA engagement in CBR difficult, including: HIV-related stigma; health-related challenges; "credentialism"; lack of capacity to engage in research; other issues taking priority; and mistrust of researchers. Facilitating factors included valuing lived experience; training and mentoring opportunities; financial compensation; trust building; and accommodating PLWHA's needs. While there is strong support for the GIPA principles in theory, practice lags far behind.

    There has been little research on the concrete role of the press in discourses on AIDS. This study investigated the AIDS discourses created by the major media. In particular, from the perspective of the agenda-setting theory, it examines differences in the framing of AIDS-related news depending on the political orientation and news sources of the press. This study analyzed the thematic frames and news sources implied by AIDS-related coverage. The 2 major media representing conservatism and progressivism were selected as the objects of analysis. As for the search engine for content analysis, the Korean Integrated Newspaper Database System was used, and 151 articles containing "AIDS" or "HIV" over 5 years from January 2005 to December 2010 were analyzed. According to the results of the analysis, there were the 6 following frames: aid/support, accident, human rights, risk, prevention, and biomedicine. Whereas the conservative press in South Korea continued to frame AIDS in the traditional way, the progressive press tended relatively more often to attempt new agenda setting, from the perspective of human rights and inequality. However, both newspaper companies tended mostly to select experts as the sources of AIDS news, thus continuing to exclude infectees and civil and society organizations.

    Parents with HIV/AIDS are confronted with unique challenges when discussing HIV-related information with their children. Strategies for navigating these challenges effectively have not been systematically examined. In this study, we conducted in-depth interviews with 76 parents with HIV/AIDS who had children ages 10-18 years. Guided by O'Keefe and Delia's definition of a complex communication situation and Goldsmith's normative approach to interpersonal communication, we examined parents' goals for discussing HIV-related information, factors that made conversations challenging, and instances where these conversational purposes conflicted with one another. Our data reveal the following parent-adolescent communication predicaments: relaying safety information about HIV while minimizing child anxiety, modeling open family communication without damaging one's parental identity, and balancing parent-child relational needs amid living with an unpredictable health condition. Parents also described a variety of strategies for mitigating challenges when discussing HIV-related topics. Strategies parents perceived as effective included reframing HIV as a chronic, manageable illness; keeping talk educational; and embedding HIV-related topics within more general conversations. The theoretical and practical applications of these findings are discussed with regard to their relevance to health communication scholars and HIV care professionals.

    AIDS stigmas delay HIV diagnosis, interfere with health care, and contribute to mental health problems among people living with HIV. While there are few studies of the geographical distribution of AIDS stigma, research suggests that AIDS stigmas are differentially experienced in rural and urban areas. We conducted computerized interviews with 696 men and women living with HIV in 113 different zip code areas that were classified as large-urban, small-urban, and rural areas in a southeast US state with high-HIV prevalence. Analyses conducted at the individual level (N = 696) accounting for clustering at the zip code level showed that internalized AIDS-related stigma (e.g., the sense of being inferior to others because of HIV) was experienced with greater magnitude in less densely populated communities. Multilevel models indicated that after adjusting for potential confounding factors, rural communities reported greater internalized AIDS-related stigma compared to large-urban areas and that small-urban areas indicated greater experiences of enacted stigma (e.g., discrimination) than large-urban areas. The associations between anticipated AIDS-related stigma (e.g., expecting discrimination) and population density at the community-level were not significant. Results suggest that people living in rural and small-urban settings experience greater AIDS-related internalized and enacted stigma than their counterparts living in large-urban centers. Research is needed to determine whether low-density population areas contribute to or are sought out by people who experienced greater AIDS-related stigma. Regardless of causal directions, interventions are needed to address AIDS-related stigma, especially among people in sparsely populated areas with limited resources.

This research was part of a larger project, Tswaragano, conducted in the North-West Province, South Africa, which explored and described the competence, ability and strengths of the family of the HIV-positive patient during home support. This research focused on Potchefstroom in the North-West Province. This article focuses on research with the objective being to explore and describe the comprehension of HIV-positive patients and their families with regard to HIV- and AIDS-related information, and to formulate recommendations to improve their comprehension of this information. A quantitative, explorative and descriptive survey design was followed. Data were collected by means of questionnaires completed by HIV-positive patients (n = 79 and their family members (n = 34. Descriptive statistical analysis by means of frequency analysis was conducted. Ethical considerations and mechanisms to enhance validity and reliability are discussed. The results indicated that both HIV-positive respondents and their families face social and financial challenges due to unemployment and low income. A strength found in this research is that the majority of respondents are linked to a church, which can be a valuable platform to share information on HIV and AIDS. With regards to sharing, sources and comprehension of HIV- and AIDS-related information, it is apparent that respondents perceived that pre- and post-counselling provided an opportunity for information sharing, but that they need health care workers to spend more time with them, to be non-judgemental and to make more use of visual aids. It furthermore seems that the majority of HIV-positive respondents in this study did comprehend the need for and negotiate for safer sexual practices. It was concluded that

    The purpose of this article was to report identified barriers and challenges experienced in the recruiting process of Chinese American adolescents to a cross-sectional HIV/AIDS-related study. Snowball sampling method was used to recruit Chinese American adolescents from Chinese American communities in a U.S. Midwestern state. Barriers and challenges to recruitment were reviewed and analyzed from Chinese cultural perspectives in the hope of aiding researchers and health care providers understand and facilitate future recruitment of Chinese Americans for HIV/AIDS prevention studies. Barriers to recruitment were found related to the taboo topic of sexual issues in Chinese culture, unawareness and denial of HIV/AIDS risks, authoritarian parenting style in Chinese culture, and the required active consents. Facilitating factors of recruiting Chinese American adolescents to future HIV/AIDS prevention research or intervention programs are discussed. Information provided in this article may increase nurses' awareness of various barriers that they might encounter when they conduct research or address HIV/AIDS-related topics of Chinese American adolescents.

    To compare the effects of oral suspensions of megestrol acetate, 800 mg/d, and placebo on body weight in patients with acquired immunodeficiency syndrome (AIDS)-related weight loss. Randomized, double-blind, placebo-controlled trial. Outpatient community and university patient care setting. Consecutive patients with AIDS who had substantial weight loss and anorexia were enrolled. Of 271 patients, 270 and 195 were evaluable for safety and efficacy, respectively. Patients were randomly assigned to receive placebo or megestrol acetate (100 mg, 400 mg, or 800 mg) daily for 12 weeks. The primary efficacy criterion was weight gain. Patients were evaluated at 4-week intervals for changes in weight and body composition, caloric intake, sense of well-being, toxic effects, and appetite. For evaluable patients receiving 800 mg of megestrol acetate per day, 64.2% gained 2.27 kg (5 pounds) or more compared with 21.4% of patients receiving placebo (P < 0.001). An intent-to-treat analysis showed significant differences (P = 0.002) between those receiving placebo and those receiving 800 mg of megestrol acetate for the number of patients who gained 2.27 kg (5 pounds) or more (8 of 32 [25%] compared with 38 of 61 [62.3%], respectively). Compared with patients receiving placebo at the time of maximum weight change, evaluable patients receiving megestrol acetate, 800 mg/d, reported improvement in overall well-being and had an increase in mean weight gain (-0.725 compared with 3.54 kg [-1.6 compared with +7.8 pounds]; P < 0.001), lean body mass (-0.772 compared with +1.14 kg [-1.7 compared with +2.5 pounds]; P < 0.001), appetite grade (P < 0.001), and caloric intake (-107 compared with +645.6 calories/d; P = 0.001). In patients with AIDS-related weight loss, megestrol acetate can stimulate appetite, food intake, and statistically significant weight gain that is associated with a patient-reported improvement in an overall sense of well-being.

    Changing a complex Computer Aided design profile such as car and aircraft surfaces has always been difficult and challenging. The capability of CAD software such as AutoCAD and CATIA show that a simple configuration of a CAD design can be easily modified without hassle, but it is not the case with complex design configuration. Design changes help users to test and explore various configurations of the design concept before the production of a model. The purpose of this study is to look into macros programming as parametric method of the commercial aircraft design. Macros programming is a method where the configurations of the design are done by recording a script of commands, editing the data value and adding a certain new command line to create an element of parametric design. The steps and the procedure to create a macro programming are discussed, besides looking into some difficulties during the process of creation and advantage of its usage. Generally, the advantages of macros programming as a method of parametric design are; allowing flexibility for design exploration, increasing the usability of the design solution, allowing proper contained by the model while restricting others and real time feedback changes.

    Neuroimmune pharmacology (NIP) can be considered a multidisciplinary science where areas of neuroscience, immunology, and pharmacology intersect in neurological disorders. The R25 training program titled "Translational Research in NeuroAIDS and Mental Health (TR-NAMH): An innovative mentoring program to promote diversity in NeuroAIDS Research (R25 MH080661)" at the Johns Hopkins University is a web-based interactive course with the goal to improve the capacity of high quality research by developing mentoring programs for (1) doctoral and postdoctoral candidates and junior faculty from racial and ethnic minorities and (2) non-minority individuals at the same levels, whose research focuses on NeuroAIDS disparity issues such as HIV-associated neurocognitive disorders (HAND). This web-based interactive course overcomes the limitations of traditional education such as access to expert faculty and financial burden of scientists from racial and ethnic minority groups in the field of NeuroAIDS research and NIP and identifies rich nurturing environments for investigators to support their careers. The TR-NAMH program identifies a cadre of talented students and investigators eager to commit to innovative educational and training sessions in NeuroAIDS and NIP. The interplay between NIP changes precipitated by HIV infection in the brain makes the study of HAND an outstanding way to integrate important concepts from these two fields. The course includes activities besides those related to didactic learning such as research training and long-term mentoring; hence, the newly learned topics in NIP are continually reinforced and implemented in real-time experiences. We describe how NIP is integrated in the TR-NAMH program in the context of HAND.

    1997-01-01

    This research thesis addresses the use of a membrane-based technique, nano-filtration, aided or not by complexation, for the processing of highly saline liquid effluents produced by radio-chemical decontamination. The objective is to separate non-radioactive elements (sodium nitrate) from radio-elements (caesium, strontium and actinides) in order to reduce the volume of wastes. Within the perspective of an industrial application, a system to concentrate the effluent is firstly defined. Different nano-filtration membranes are tested and reveal to be insufficient in highly saline environment. A stage of selective complexation of radio-elements is therefore considered before nano-filtration. The main factors affecting performance of nano-filtration-complexation (for a given membrane system) are identified: ionic force, pH, ligand content, trans-membrane pressure. Finally, a nano-filtration pilot is implemented to perform nano-filtration-complexation operations by remote handling on radioactive substances [fr

    Mononuclear cells were obtained from 71 human immunodeficiency virus type 1 (HIV-1) seropositive subjects presenting and first visit either as asymptomatic or with minor symptoms and with CD4 lymphocytes greater than 550 per mm3 (group A, 35 patients) or as patients with AIDS, AIDS-related illnesses, or CD4 lymphocytes less than 400 per mm3 (group B, 36 patients). After 1-5 years of follow-up, 13 patients of group A had essentially retained their initial status (asymptomatics); the 22 others had suffered clinical or immunological deterioration (progressors). Frozen cells were thawed and submitted to lethal gamma-irradiation in vitro (4500 rads; 1 rad = 0.01 Gy) before they were cultured with normal phytohemagglutinin-stimulated lymphocytes to determine radiation-resistant HIV expression ex vivo (R-HEV). HIV antigenemia correlated with R-HEV values in 142 samples (r = 0.92, P less than 0.001) but was a less sensitive predictor of disease than R-HEV. R-HEV was detected in all specimens from patients with major AIDS-related illnesses or HIV-associated CD4 lymphopenia. In 77% of the progressors from group A, R-HEV detection preceded the onset of AIDS-associated disease or CD4 lymphopenia by 1 year (average). Conversely, R-HEV was low or was not detected in 36 sequential specimens from the 13 patients who remained asymptomatic over the following 2-5 years. Thus, persistently low HIV expression in vivo predicted a nondiseased state, whereas higher HIV expression levels seemed necessary for disease to occur. These data indicate that R-HEV is related to productive HIV infection in vivo, the latter acting as a determinant of AIDS-related illnesses. In view of this, measurement of HIV expression levels in the patient should be useful in antiviral efficacy trials

    Full Text Available Latin America is the region with the third most AIDS-related cryptococcal meningitis infections globally. Highly active antiretroviral therapy (HAART has reduced the number of infections; however, the number of deaths and the case-fatality rate continues to be unacceptable. In this review, we focus on the burden of AIDS-related cryptococcosis in Latin America and discuss potential strategies to reduce early mortality from Cryptococcus. In this review, we highlight the importance of: (1 earlier HIV diagnosis and HAART initiation with retention-in-care to avoid AIDS; (2 pre-HAART cryptococcal antigen (CRAG screening with preemptive fluconazole treatment; (3 better diagnostics (e.g. CRAG testing; and (4 optimal treatment with aggressive management of intracranial pressure and induction therapy with antifungal combination. Implementation of these strategies can reduce cryptococcal-related deaths, improve care, and reduce healthcare costs.

    Full Text Available Research on the etiology of adult psychopathology and its relationship with childhood trauma has focused primarily on specific forms of maltreatment. This study developed an instrument for the assessment of childhood and adolescence trauma that would aid in identifying the role of co-occurring childhood stressors and chronic adverse conditions. The Complex Trauma Questionnaire (ComplexTQ, in both clinician and self-report versions, is a measure for the assessment of multi-type maltreatment: physical, psychological, and sexual abuse; physical and emotional neglect as well as other traumatic experiences, such rejection, role reversal, witnessing domestic violence, separations, and losses. The four-point Likert scale allows to specifically indicate with which caregiver the traumatic experience has occurred. A total of 229 participants, a sample of 79 nonclinical and that of 150 high-risk and clinical participants, were assessed with the ComplexTQ clinician version applied to Adult Attachment Interview (AAI transcripts. Initial analyses indicate acceptable inter-rater reliability. A good fit to a 6-factor model regarding the experience with the mother and to a 5-factor model with the experience with the father was obtained; the internal consistency of factors derived was good. Convergent validity was provided with the AAI scales. ComplexTQ factors discriminated normative from high-risk and clinical samples. The findings suggest a promising, reliable, and valid measurement of early relational trauma that is reported; furthermore, it is easy to complete and is useful for both research and clinical practice.

    Full Text Available This paper aims to describe the psychometric properties of a new brief multidimensional scale to measure HIV/AIDS related attitudes for adolescents, the HIV Attitudes Scale (HIV-AS. Exploratory analysis aimed to find the theory-driven structure and to develop an empirically derived factor structure for HIV-AS, which was tested with a confirmatory factor analysis. Factorial invariance was studied across gender and age, and multigroup structural equation approach was used in order to compare the groups. Reliability, convergent and discnmmant validity were examined. The analyses were based on a sample of 1216 Spanish adolescents. The instrument consists of 12 items distributed across four major factors: 1 Attitudes towards safe sex when there are obstacles, 2 Attitudes towards the HIV test, 3 Attitudes towards condom use, and 4 Attitudes towards people living with the AIDS. The HIV-AS shows good validity and internal reliability and equivalent four-factor structure across gender and the three age groups studied. It can be consider as a capable and parsimonious self-report scale for assessing major aspects of HIV/AIDS-related attitudes for adolescents.

    1986-01-01

    As the number of cases of AIDS increases, more and more companies will have to decide how to handle employees with AIDS and those at high risk. AIDS creates medical, legal, and ethical issues in the workplace, all of which are emotional and complex; managers need expert assistance to guide their decision-making and policy development. This article identifies various dimensions of the AIDS-related issues emerging in corporations nationwide, including: confidentiality, the right of patients to work, benefits and insurance, HTLV-III screening, fears of contagion among workers, needs of companies to avoid financial and legal exposure, and effects on worker productivity. Health educators are in a unique position to contribute to the satisfactory resolution of AIDS-related problems in the workplace through their training and experience in education, policy development and the relevant legal and ethical issues in the health care field. However, they will have to initiate discussions with corporation executives themselves in order to reach this most important audience.

    This paper provides a framework analysing the response of South African companies to HIV/AIDS. Drawing on three case studies of companies, each with over 20,000 South African-based employees, we identify six 'drivers' that influence corporate behaviour regarding HIV/AIDS: legal requirements, voluntary regulation, business costs, social pressures, visibility of the disease, and individuals within companies. We suggest that costs calculations, while possibly underestimating indirect and macro-implications, are not key in driving company responses to HIV/AIDS. The law and voluntary regulation have influenced, but not determined, the response of companies to HIV/AIDS. Social pressures on companies are of importance, but the scale and complexity of need in South Africa has seen the deflecting of this driver. Of greater reference in determining responses has been the social pressure of other companies' responses. The general visibility of the AIDS epidemic is also a significant factor in explaining companies' responses to HIV/AIDS. Moreover, the visibility of HIV/AIDS within companies has influenced the responses of often relatively weak, internal agents who have been attempting to drive companies' HIV/AIDS programmes. We conclude that external drivers--legal requirements, economic performance, and social pressures--have framed corporate responses to HIV/AIDS to a degree, but have generally been weak. Moreover, there has been relatively little synergy between these external drivers and the internal drivers--voluntary regulation, visibility, and company HIV/AIDS 'champions'--that could propel companies into pro-active, bold responses to HIV/AIDS.

    To investigate the awareness of acquired immune deficiency syndrome (AIDS) knowledge and AIDS-related behaviors among youth students in gay dating sites, and to provide evidences for AIDS prevention education through the internet. The students in gay dating sites, selected by a snowball sampling, were interviewed by questionnaires. Chi-square tests were used to analyze the awareness of AIDS knowledge among the students of different characteristics. The Logistic regression was used to analyze the factors associated with ever testing for HIV. In the study, 469 youth students in gay dating sites filled in the questionnaires, and a total of 442 (94.2%) valid samples were collected. The awareness of HIV/AIDS knowledge for the public among the youth students in gay dating sites was 83.9% (371).The awareness of HIV/AIDS knowledge for the youth students was 77.1% (341), and the rate of ever testing for HIV was 52.0% (230). The awareness of HIV/AIDS knowledge for the public in the students were different in different age groups (P=0.001), different marital statuses (Pdating sites was 75.1% (332), and the rate of multiple sexual partnerships among the youth students was 41.3% (137). Compared with homosexual orientation, sexual orientation as heterosexual (OR=0.282, 95%CI: 0.151 to 0.528) and not sure (OR=0.175, 95%CI: 0.035 to 0.885) were risk factors of ever testing for HIV. Multiple sexual partnerships (OR=2.103, 95%CI: 1.278 to 3.462) were promoting factors of ever testing for HIV. The rate of high-risk behaviors among the youth students in gay dating sites was high. The concern should be raised to heterosexual male students who had tendency to homosexual behavior. The AIDS prevention education should be developed in gay dating sites, to improve the self-protection awareness of the youth students.

    Complex Emergencies are an international Public Health problem currently becoming increasingly more frequent and of growing proportions which lead to major death and disease rates, especially during the acute stage thereof. This study is aimed at identifying and analyzing the top-priority areas of intervention in the acute stage of a complex emergency drafted in the operating manuals of the main aid agencies, as well as the degree of development and structuring of the activities proposed in each area on which priority has been placed. The intervention manuals drafted by nine major aid agencies were used as study material. A quantitative analysis was then made of the 16 intervention priorities set out, as well as of the degree to which each priority was defined based on the development of 73 variables of aspects of the proposals set out in the manuals. The ACNUR manual includes 90% of the 73 variables for further expansion upon the priorities, the UN Humanitarian Affaire Coordination Office manual including 35% of the 73 variables. ACNUR better expands upon the non-healthcare variables, followed by MSF and USAID. Doctors without borders shows a 97.3% degree of expansion of the healthcare variables) followed by ACNUR (94.7%), USAID (92.1%). ACNUR has been found to have the most integral proposal, the UN Humanitarian Affairs Coordination Office having the most discreet. There is a general trend towad further expanding upon and unifying the health indicators, whilst other aspects are not further expanded upon.

    AIDS-related knowledge, attitudes, and behaviors were assessed in female Mexican migrant laborers. Thirty-two women were administered a modified version of the Hispanic Condom Questionnaire. Respondents were knowledgeable about the major modes of HIV transmission, but one-third to one-half of the women believed that they could contract AIDS from unlikely casual sources. Although respondents reported few negative beliefs about condom use, actual condom use with sex partners was low and knowledge of proper condom use was problematic. Consequently, 75 percent reported never carrying condoms. Implications of these findings for future research and provision of services for female Mexican migrants are discussed.

    With the lengthening of life expectancy among HIV-positive subjects related to the use of highly active antiretroviral treatments, an increased risk of cancer has been described in industrialized countries. The question is to determine what occurs now and will happen in the future in the low income countries and particularly in sub-Saharan Africa where more than two-thirds of all HIV-positive people live in the world. The objective of our paper is to review the link between HIV and cancer in sub-Saharan Africa, putting it in perspective with what is already known in Western countries. Studies for this review were identified from several bibliographical databases including Pubmed, Scopus, Cochrane, Pascal, Web of Science and using keywords "HIV, neoplasia, epidemiology and Africa" and related MesH terms. A clear association was found between HIV infection and AIDS-classifying cancers. In case-referent studies, odds ratios (OR) were ranging from 21.9 (95% Confidence Interval (CI) 12.5-38.6) to 47.1 (31.9-69.8) for Kaposi sarcoma and from 5.0 (2.7-9.5) to 12.6 (2.2-54.4) for non Hodgkin lymphoma. The association was less strong for invasive cervical cancer with ORs ranging from 1.1 (0.7-1.2) to 1.6 (1.1-2.3), whereas ORs for squamous intraepithelial lesions were higher, from 4.4 (2.3-8.4) to 17.0 (2.2-134.1). For non AIDS-classifying cancers, squamous cell conjunctival carcinoma of the eye was associated with HIV in many case-referent studies with ORs from 2.6 (1.4-4.9) to 13.0 (4.5-39.4). A record-linkage study conducted in Uganda showed an association between Hodgkin lymphoma and HIV infection with a standardized incidence ratio of 5.7 (1.2-17) although OR in case-referent studies ranged from 1.4 (0.7-2.8) to 1.6 (1.0-2.7). Other cancer sites found positively associated with HIV include lung, liver, anus, penis, vulva, kidney, thyroid and uterus and a decreased risk of female breast cancer. These results so far based on a relatively small number of studies warrant

    The number of acquired immunodeficiency syndrome (AIDS)-related deaths covers different segments of the population differently, making monitoring of this mortality essential. The aim of this study was to describe the epidemiological situation of AIDS-related mortality in a municipality in the northeastern region of Brazil. Retrospective cross-sectional study based on data from death certificates in the mortality information system of the Health Information Center, Municipal Health Foundation, Brazil. Between 2003 and 2013, we investigated death certificates on which AIDS-related mortality was reported. Sociodemographic data, year, place, type of establishment where death occurred and underlying and associated causes that led to AIDS-related death were described. The Mann-Kendall test was used to verify the growth trend of the standardized mortality rate over the period studied. Among the 1,066 AIDS-related deaths, 69.7% were among men; 47.2% of the individuals were 28-41 years of age, 32.7% had had 4-7 years of schooling, 66.9% were pardos (mixed race), 55.7% were unmarried and 15.3% were housekeepers. Hospitals were the site of 97% of the deaths, and 91% occurred at public hospitals. Respiratory failure was the main cause of death. The prevalence of infectious and parasitic diseases was 99.0%. AIDS-related mortality increased by 160% over the period studied, from 5.5/100,000 inhabitants in 2003 to 14.3/100,000 in 2013. In the Brazilian municipality studied here, AIDS-related mortality was most prevalent among men and young adults of lower socioeconomic level. Over the period studied, the mortality rate increased.

    We tested whether observation of the presence and relationship of attendants (i.e. those that accompany upon admission) and visitors to a sample of 230 (128 male, 102 female) married HIV-positive people in an HIV care centre provides an indicator of caregiving, AIDS-related stigma and discrimination. Sensitivity to gender, location (urban vs. rural), age (35) and source of infection (spouse vs. non-spouse) were factors considered to modulate AIDS-related stigma and assess discrimination. HIV-positive people were accompanied by their spouse (53%), mother (14%), father (7%), with only 7% attending alone. Immediate family most commonly accompanied on admission (80%), but visitors were mainly from the 'extended' family (32%) with many receiving no visitors (48%). Females (11%) were more likely than males to attend alone (11% vs. 4%; prate of no visitors than persons not infected by their spouse (54% vs. 40%; pdiscrimination. The measure appears particularly sensitive to the gender of the HIV-positive person. Such a measure may aid healthcare professionals to focus resources such as relational counselling upon the family and close friends of people experiencing AIDS-related stigma and discrimination, with the aim of improving the provision of care within the community.

    Systemic non-Hodgkin lymphoma (S-NHL) is a common malignancy during HIV infection, and it is hypothesized that infectious agents may be involved in the etiology. Epstein-Barr virus DNA is found in <40% of patients with AIDS-related S-NHL, suggesting that other oncogenic viruses, such as polyomaviruses, may play a role in pathogenesis. We analyzed AIDS-related S-NHL samples, NHL samples from HIV-negative patients, peripheral blood leukocytes from HIV-infected and -uninfected patients without NHL, and lymph nodes without tumors from HIV-infected patients. Specimens were examined by polymerase chain reaction analysis with use of primers specific for an N-terminal region of the oncoprotein large tumor antigen ( T-ag ) gene conserved among all three polyomaviruses (simian virus 40 [SV40], JC virus, and BK virus). Polyomavirus T-ag DNA sequences, proven to be SV40-specific, were detected more frequently in AIDS-related S-NHL samples (6 of 26) than in peripheral blood leukocytes from HIV-infected patients (6 of 26 vs. 0 of 69; p =.0001), NHL samples from HIV-negative patients (6 of 26 vs. 0 of 10; p =.09), or lymph nodes (6 of 26 vs. 0 of 7; p =.16). Sequences of C-terminal T-ag DNA from SV40 were amplified from two AIDS-related S-NHL samples. Epstein-Barr virus DNA sequences were detected in 38% (10 of 26) AIDS-related S-NHL samples, 50% (5 of 10) HIV-negative S-NHL samples, and 57% (4 of 7) lymph nodes. None of the S-NHL samples were positive for both Epstein-Barr virus DNA and SV40 DNA. Further studies of the possible role of SV40 in the pathogenesis of S-NHL are warranted.

    This study offers the first systematic analysis of the impact of press-state relations, or media systems, on the HIV/AIDS news agenda in African news coverage. The premise is that media systems play a determining role in the degree to which journalists can independently advocate for social change when covering HIV/AIDS. Drawing on comparative research, four sub-Saharan countries were categorized into two media systems: Contained Democratic (South Africa, Nigeria) and Repressive Autocratic (Zimbabwe, Kenya). A sample of HIV/AIDS stories (n = 393) published from 2002-2007 in each country's leading Anglophone newspaper was content analyzed. Across all coverage, the topic of social costs was framed more for the responsibility borne by nongovernmental agents than governmental agents. In Contained Democratic media systems, however, story emphasis shifted toward government agents taking responsibility for addressing the social costs of HIV/AIDS. Prevention campaigns were framed more as progress than decline across all newspapers; however, campaigns were reported as being more efficacious in Contained Democratic systems than in Repressive Autocratic systems. No impact of media system on framing of medical developments was found. Results show the value of comparative analysis in understanding the agenda-setting process: with greater emphasis on positive efficacy and government initiative, the news agenda in Contained Democratic media systems can facilitate stronger positive societal-level responses than the news agenda in Repressive Autocratic media systems.

    Full Text Available This paper analyzes the Official Development Aid (AOD that has as its source Taiwan and as its destination Central America. It has three basic aims: Firstly, there is a huge bibliographic vacuum on the topic of these pages. Beginning filling it is an academic need. Even some intellectuals feel that they should lean against either Beijing or Taipei, that if they write on Taiwan they should defend or attack one of the contending parties. Here it is seen that a study close to objectivity is possible. Secondly, most of the research in International Relations has been focused on topics related with power itself or with just elements related with hard power. AOD is both hard and soft power, therefore this paper shades light to the dark side partially viewing international relations from a theoretical perspective were interactions help to construct identities and cooperation is an essential variable of world politics. Finally, it will be seen below that the Taiwanese cooperativeeconomic actions are helpful to the progress of poor parts of the Central American region and are helpful to create domestic markets with strong links with the world market deepening the economic integration both regional and global. Aid from Taiwan and some other countries, mainly through the transmission of know how, could be of assistance in surmounting huge troubles. Aid is vital because some of Central American’s problems are being exported mainly to México and the United States under the form, just to give an example, of Mara Salvatrucha gangs source of violence and drug trafficking. It is not meaningless to stress that Taiwanese ODA is by far not enough and is very small in the international context.

    Thirty patients suffering from AIDS have been examined in this study. The stage of infection of the patients was defined according to the criteria of the Center for Disease Control, so that the study covered 22 patients with manifest AIDS, and 8 patients with AIDS-related complex. The lung scans have been made in all patients 48 and 72 hours after i.v. injection of 185 MBq of 67 Ga citrate, taking ventral and dorsal images with the gamma camera. In the scans recorded after 72 hours, ROI technique has been used to quantify the lung uptake and to put it in relation to uptake data of the soft neck tissue. The results show that gallium scintiscanning is far more sensitive in detecting opportunistic pneumonia in AIDS patients than is conventional chest radiography. If the latter detected any signs at all, the gallium scan did so about one to two weeks earlier in about one third of the patients. Pathologic accumulation in the scintiscan exceeding the range shown by the correlated radiograph indicate that in single cases extension of pneumonia can be underestimated when assessed by the radiograph alone.

    Full Text Available Background: India estimates third highest number of HIV infections in the world, with about 2.4 million people currently living with HIV/AIDS. Adequately trained and sensitized healthcare professionals can play a vital role in combating this epidemic. Limited studies have explored knowledge and attitudes of medical students relating to HIV/AIDS, particularly in the eastern part of India. Methods: The present cross sectional study explored knowledge and attitudes of first year MBBS, BDS & BPT students of Kalinga Institute of Medical Sciences (KIMS, Bhubaneswar, Odisha on HIV/AIDS using a self-administered questionnaire. Data thus collected were analyzedand relevant statistics were calculated. Knowledge and attitude scores were determined and analysis of variance (ANOVA test was used to examine the equality between the groups. Results: All students scored low on the overall knowledge scale (<10/15. Specifically, knowledgewas low on modes of transmission and treatment. Attitudinal scores in the areas of precautions and need for training on HIV was low for all the three streams.The willingness to treat HIV/AIDS patient was found to be high amongst study participants. Conclusion: There is a need and scope to provide correct and detailed information on HIV/AIDS for new entrants in medical and allied health sciences to help them acquire adequate knowledge and develop appropriate attitudes towards HIV/AIDS.

    Full Text Available Abstract Background China is currently facing a rapid and widespread increase in human immunodeficiency virus (HIV/acquired immunodeficiency syndrome (AIDS. The activities of female sex workers (FSWs have contributed to the mounting epidemic of HIV/AIDS and other sexually transmitted diseases (STDs. Therefore, this study aimed to assess the HIV/AIDS-related knowledge, attitude and risk behaviors among FSWs operating in Shanghai China. Methods A cross-sectional study was conducted in five districts of Shanghai, including three suburbs and two downtown locales. We adopted a cluster randomized sampling method to obtain ten geographic sites which consisted of one or more communities/villages proximal to a location where FSWs were accessible. A total of 324 FSWs from 109 Xitou Fang, massage parlors and hair salons who explicitly provided sexual services were enrolled in the study. Each participant completed a questionnaire survey and interview aimed to collect information on the individual's knowledge, attitude, and behaviors associated with risk for HIV/AIDs. Results The overall correct answer rate of HIV/AIDS-related knowledge was 60.8%, and the knowledge of FSWs from downtown areas was significantly higher than those from suburban areas (P P Conclusions Based on the findings from our survey, we advise that promotion of HIV/AIDS-related knowledge be targeted towards FSWs in Shanghai, especially those operating in the suburbs. HIV prevention efforts, such as urging constant condom usage with both clients and steady partners, should be sustained and reinforced among the female sex workers population.

    Objective: To reveal the prevalence and the related factors of hepatitis B (HepB) virus infection among HIV/AIDS patients. Methods: We conducted a cross-sectional study in two HIV clinics, affiliated to local Centers of Disease Control and Prevention in Guangxi Zhuang Autonomous Regional. A face-to-face interview, with questionnaire was conducted to collect information on socio-demographic characteristics, drug use, and sexual behavior. Blood samples were used to test HBsAg. χ (2) test or Fisher's exact test and unconditional logistic regression models were used to identify the influencing factors. Results: The prevalence of HBV and HIV co-infection was 13.85% (113/816). Results from multivariate logistic regression analyses showed that age (25-45), family history of HBV and history of HepB vaccination were independent influencing factors for HBV and HIV coinfection, with OR (95% CI ) as 1.738 (1.031-2.931), 2.898 (1.678-5.005) and 1.744 (1.052-2.892), respectively. Conclusion: The prevalence of HBV among HIV/AIDS patients was significantly higher than that in general population. HIV/AIDS patients aged between 25 and 45 and with family history of HBV were more likely to be infected with HBV, while HepB vaccination was associated with the reduction of HIV/HBV coinfection. Specific comprehensive prevention and treatment programs on HIV/AIDS patients need to be set up.

    The administration of first aid in burns has been shown to have a significant influence on the ultimate severity of the burn. We wanted to assess in-hospital healthcare (HCW), and non-healthcare workers' (nHCW) knowledge of first aid in burns. A purpose-designed questionnaire, including information about previous attendance at a first aid course and four clinical scenarios of burns, was distributed to HCWs in the local hospitals and non-medical students in the Universities of Leeds and Sheffield. 697 questionnaires were completed - 397 (57%) from HCW and 300 (43%) from nHCW. 59% of HCW had attended a first aid course, 68% of these courses included teaching on first aid in burns. HCW who had completed a first aid course generally did better than those who had not. Only 16% of HCW achieved correct answers in all questions compared to 30% nHCW. We show that the knowledge of first aid in burns is relatively poor amongst HCW and that attendance at a burns first aid course improves knowledge (although perhaps not as much as one might hope). We recommend that the burns content of first aid courses be reviewed, and that there is a requirement for ALL hospital healthcare workers to undertake a first aid course, which includes appropriate burns first aid.

    Brain glucose metabolism was evaluated in four patients with acquired immunodeficiency syndrome (AIDS) dementia complex using [ 18 F]fluorodeoxyglucose (FDG) and positron emission tomography (PET) scans at the beginning of therapy with 3'-azido-2',3'-dideoxythymidine (AZT, zidovudine), and later in the course of therapy. In two patients, baseline, large focal cortical abnormalities of glucose utilization were reversed during the course of therapy. In the other two patients, the initial PET study did not reveal pronounced focal alterations, while the post-treatment scans showed markedly increased cortical glucose metabolism. The improved cortical glucose utilization was accompanied in all patients by immunologic and neurologic improvement. PET-FDG studies can detect cortical metabolic abnormalities associated with AIDS dementia complex, and may be used to monitor the metabolic improvement in response to AZT treatment

    The prevalence of HIV/AIDS in Chinese ethnic minorities is an important component of China's AIDS issues. In this study, we launched an intervention programme in Yunnan Province of China, where the Dai people live, to carry out the community-based HIV/AIDS health education and behavioral interventions on ordinary Dai farmers. The Dai people believe in Theravada Buddhism. Four rural communities were randomly divided into two groups. In one group (Buddhist group), HIV/AIDS health education and behavioral intervention were carried out by monks. The other group (women group) was instructed by women volunteers. The intervention continued for one year and the data were collected before and after the intervention project. In the Buddhist group, the villagers' AIDS related knowledge score was boosted from 3.11 to 3.65 (P Buddhist group, the villager's attitude score towards the people living with HIV and AIDS (PLWHA) also increased significantly from 1.51 to 2.16 (P Buddhist organization has limited success in promoting the use of condoms, but plays an important role in eliminating HIV/AIDS related discrimination.

    An enabling environment is believed to have significant and critical effects on HIV and AIDS program implementation and desired outcomes. This paper estimates the paths, directionality, and direct and indirect associations between critical enablers with antiretroviral treatment (ART) coverage and to AIDS-related mortality. Frameworks that consider the role of enablers in HIV and AIDS programs were systematically reviewed to develop a conceptual model of interaction. Measurements for constructs of the model were pooled from the latest publicly available data. A hypothetical model, including latent/unobserved factors and interaction of enablers, program activities and outcomes, was analyzed cross-sectionally with structural equation modeling. Coefficients of the model were used to estimate the indirect associations of enablers to treatment coverage and the subsequent associated impact on AIDS related mortality. The model's fit was adequate (RMSEA = 0·084, 90% CI [0·062, 0·104]) and the indirect effects of enablers on outcomes were measured. Enablers having significant associations with increased ART coverage were social/financial protection, governance, anti-discrimination, gender equality, domestic AIDS spending, testing service delivery, and logistics. Critical enablers are significantly correlated to outcomes like ART coverage and AIDS related mortality. Even while this model does not allow inference on causality, it provides directionality and magnitude of the significant associations.

    Full Text Available Background & aim: AIDS is one of the major public health challenges all over the world. Perceived risk is a significant predictor of high-risk behaviors related to AIDS. Women constitute more than half of the HIV patients, and the rate of female sex workers with AIDS is more than the rest of female population. Therefore, the present study aimed to evaluate AIDS risk perception and its related factors in females with high-risk behaviors in Mashhad, Iran. Methods:This descriptive study was performed on 58 women who were arrested on prostitution charges and imprisoned in Mashhad Vakil Abad Prison in 2013. The data were collected using self-designed questionnaires assessing knowledge regarding AIDS as well as sexual activities and also perceived risk of HIV questionnaire. One-way ANOVA, independent samples t-test, linear regression, and Chi-square tests were run, using SPSS version 16. Results: The mean score of HIV risk perception was 18.43±5.92, which was average. There was a significant relationship between the mean score of perceived risk of HIV and knowledge regarding AIDS (P=0.005, alcohol consumption (P=0.04, history of addiction (P=0.008, using contraceptive methods (P=0.01, condom use during intercourse (P=0.02, voluntary HIV testing (P=0.001, and follow-up of HIV test (P=0.009. Conclusion:The findings of the present study revealed that knowledge, alcohol consumption, history of addiction, contraceptive methods, the rate of condom use during intercourse, as well as voluntary HIV testing and follow-up were associated with perceived risk of HIV infection. Therefore, taking the necessary steps towards health promotion through appropriate training and interventional approaches seems to be mandatory for reducing high-risk behaviors in populations with low risk perception.

    This study examines the social anxieties associated with HIV prevention in adolescents in three African countries (Nigeria, Kenya, and Zimbabwe). The subjects used in this study were black Africans in form 2 or grade 10 in public high schools (Nigeria, n = 387; Kenya, n = 274; Zimbabwe n = 313). Subjects responded to the 33 item AIDS Social Assertiveness Scale (ASAS). Data indicated similar factor structures for each of the three countries and included five factors. The combined sample factor intercorrelations were modestly but significantly correlated. The mean scores for each factor were compared, and ANOVA of the factors by country, by gender, and by interaction between country and gender were performed. The factor structures were very similar between countries, each including five factors that had similar themes: condom interactions, refusal of risk, confiding in significant others, contact with people with HIV/AIDS, and general assertiveness. These factor structures were also very similar to one found in previous studies of Australian adolescents on the ASAS. The Kenyan means for four of the five factors were significantly lower than those for Nigeria, and were also significantly lower than the Zimbabwean means for two of the five factors, suggesting that Kenyan students are less anxious about social situations related to HIV/AIDS than others. Significant variance was found for several factors due to gender, country, and the interaction between gender and country. These results have important implications for designing education programs. The similarities of anxieties regarding HIV/AIDS social situations suggest that these clusters of social barriers to reduction of HIV infection risk might form the basis of educational interventions, and that dimensions of HIV social anxieties are similar across countries.

    The prevalence of symptoms in HIV disease can be associated with HIV disease itself, comorbid illness, and/or antiretroviral therapy. Unhealthy substance use behaviors, particularly substance-use behaviors including heavy alcohol intake, marijuana use, other illicit drug use, and cigarette smoking, are engaged in by many HIV-positive individuals, often as a way to manage disease-related symptoms. This study is a secondary data analysis of baseline data from a larger randomized-controlled trial of an HIV/AIDS Symptom Management Manual. In the present study, the prevalence and characteristics of unhealthy substance use behaviors in relation to HIV/AIDS symptoms are examined. Subjects were recruited from a variety of settings which provide HIV/AIDS care and treatment. The mean age of the sample (n=775) was 42.8 years (SD=9.6) and nearly thirty-nine percent (38.5%) of the sample was female. The racial demographics of the sample were: 28% African American, 28% Hispanic, 21% White/Caucasian, 16% African from Kenya or South Africa, 1% Asian, and 5% self-described as “Other.” The mean number of years living with HIV was reported to be 9.1 years (SD=6.6).Specific self-reported unhealthy substance-use behaviors were use of marijuana (n= 111; 14.3%), cigarette smoking (n=355; 45.8%), heavy alcohol use (n= 66; 8.5%), and illicit drugs (n= 98; 12.6%). A subset of individuals who identified high levels of specific symptoms also reported significantly higher substance use behaviors including amphetamine and injection drug use in addition to heavy alcohol use, cigarette smoking, and marijuana use. Implications for clinical practice include assessment of self-care behaviors, screening for substance abuse, and education of persons related to self-management across the trajectory of HIV disease.

  6. The symphony of the damned: racial discourse, complex political emergencies and humanitarian aid.

    Science.gov (United States)

    Duffield, M

    1996-09-01

    This paper concerns the manner in which the West is responding to protracted political crises beyond its borders. It examines the conceptual world-view that aid agencies bring to complex emergencies and which shapes action. The paper provides an analysis of developmentalism. That is, the currently dominant idea of development which is an adapted form of multiculturalism. It is based on the empowerment of cultural differences and the relativisation of progress. As a variant of multiculturalism, developmentalism is part of Western racial discourse. In terms of understanding conflict, it establishes a mirror-image relationship with new rascist ideas premised on cultural pluralism inevitably leading to social breakdown, violence and anarchy. To the contrary, with its functional view of social harmony, libertine developmentalism claims that even unresolved political crisis constitutes a development opportunity. Developmentalism, like culturalism generally, is incapable of analysing power. It therefore cannot understand the effects and significance of its own organisational forms. Moreover, since the absence of power translates into operational neutrality in a war zone, it is also unable to analyse the nature of new political formations emerging in the global periphery. That is, the so-called weak or failed states, warlords and so on. This functional ignorance has allowed a widespread incorporation of humanitarian aid into the fabric of political violence. Developmentalism is an essential underpinning for the growing organisational accommodation to ongoing conflict and eroding standards of justice and accountability.

    To determine the antimicrobial activity and tolerability of clarithromycin for treating bacteremic Mycobacterium avium complex disease in patients with the acquired immunodeficiency syndrome (AIDS). A randomized, double-blind, dose-ranging study. Outpatient clinics. 154 patients with human immunodeficiency virus (HIV) infection and blood cultures positive for M. avium complex who had symptomatic disease. Random assignment to clarithromycin at dosages of 500 mg, 1000 mg, or 2000 mg twice daily for 12 weeks. Median number of colony-forming units of M. avium complex per milliliter of blood. Clarithromycin decreased mycobacterial CFUs from 2.7 to 2.8 log 10/mL of blood at baseline to less than 0 log 10/mL during follow-up (P groups. Clarithromycin-resistant isolates of M. avium complex developed in 46% of patients at a median of 16 weeks. Median survival was longer in patients assigned to 500 mg twice daily (median, 249 days) than in patients assigned to 1000 mg or 2000 mg. Death in the first 12 weeks was lowest in the 500-mg group (P = 0.007). Clarithromycin therapy acutely decreased M. avium complex bacteremia in patients with HIV infection by more than 99%. Clarithromycin, 500 mg twice daily, was well tolerated and associated with better survival. Emergence of clarithromycin-resistant organisms was an important problem.

    Full Text Available Abstract: Co-infection of tuberculosis (TB-HIV/AIDS is a persistent public health problem in Brazil. This study describes epidemiological patterns and time trends of mortality related to TB-HIV/AIDS co-infection. Based on mortality data from 2000-2011 (almost 12.5 million deaths, 19,815 deaths related to co-infection were analyzed. The average age-adjusted mortality rate was 0.97 deaths/100,000 inhabitants. The highest mortality rates were found among males, those in economically productive age groups, black race/color and residents of the South region. There was a significant reduction in the mortality coefficient at the national level (annual average percent change: -1.7%; 95%CI: -2.4; -1.0, with different patterns among regions: increases in the North, Northeast and Central regions, a reduction in the Southeast and a stabilization in the South. The strategic integration of TB-HIV/AIDS control programmes is fundamental to reduce the burden of mortality related to co-infection in Brazil.

    China is currently facing a rapid and widespread increase in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). The activities of female sex workers (FSWs) have contributed to the mounting epidemic of HIV/AIDS and other sexually transmitted diseases (STDs). Therefore, this study aimed to assess the HIV/AIDS-related knowledge, attitude and risk behaviors among FSWs operating in Shanghai China. A cross-sectional study was conducted in five districts of Shanghai, including three suburbs and two downtown locales. We adopted a cluster randomized sampling method to obtain ten geographic sites which consisted of one or more communities/villages proximal to a location where FSWs were accessible. A total of 324 FSWs from 109 Xitou Fang, massage parlors and hair salons who explicitly provided sexual services were enrolled in the study. Each participant completed a questionnaire survey and interview aimed to collect information on the individual's knowledge, attitude, and behaviors associated with risk for HIV/AIDs. The overall correct answer rate of HIV/AIDS-related knowledge was 60.8%, and the knowledge of FSWs from downtown areas was significantly higher than those from suburban areas (P use of condoms was 33.6%. Condom slippage or breakage was reported as having occurred at least once by 51.2% of the FSWs. FSWs from suburban areas were found to more often engage in high-risk behaviors, including oral and anal sex, than those from downtown areas (P condom usage with these partners were lower (34.3%). Based on the findings from our survey, we advise that promotion of HIV/AIDS-related knowledge be targeted towards FSWs in Shanghai, especially those operating in the suburbs. HIV prevention efforts, such as urging constant condom usage with both clients and steady partners, should be sustained and reinforced among the female sex workers population.

    It is known that the level of HIV/AIDS-related knowledge and the degree of condom use varies by socioeconomic status (SES). However, there is limited research on the effect of mass media use on HIV/AIDS-related cognitive and behavioral outcomes in low-income countries and how it might influence the association between SES and HIV-related outcomes. We investigated the moderating effect of media use on the relationship between SES and HIV/AIDS-related knowledge and condom use in sub-Saharan Africa in terms of communication inequalities. Cross-sectional data from the Demographic Health Surveys from 13 sub-Saharan countries (2004-10) were pooled. Gender-stratified multivariable poisson regression of 151,209 women and 68,890 men were used to calculate adjusted relative ratios and 95% confidence intervals for the associations between SES, media use, HIV-related outcomes, and condom use. We found significant disparities in mass media use among people from different SES groups as well as among countries. Education and wealth are strongly and positively associated with awareness of HIV/AIDS and knowledge about transmission and prevention of HIV/AIDS and are significantly associated with condom use. These associations are attenuated when the use of various types of mass media is added to the models, with newspapers showing the strongest effect. The findings of this study suggest that media use has the potential to blunt the impact of socioeconomic status though not completely eliminate it. Thus, we need to pay attention to reducing communication inequalities among social groups and countries to moderate the effect of wealth and SES on HIV/AIDS.

    This study investigates the knowledge, attitudes and sexual practices of adolescents with mild mental retardation (MMR) in relation to HIV/AIDS. Questionnaires were personally administered to a saturation sample of 90 adolescents with MMR drawn from one specialised educational institution in Durban, South Africa. The study revealed critical gaps and erroneous beliefs regarding knowledge of HIV/AIDS, especially with regard to its existence, transmission and cure. Participants indicated a high degree of exposure to various sources of information, particularly media messages. The results indicate that gender-role prescriptions and prevailing social constructions of immorality have had a negative influence on the attitudes and behaviour of participants, particularly with regard to sexual practices and preventative risk behaviours. Furthermore, the sample was found to have low levels of self-efficacy in relation to sexual negotiation and decision-making, more specifically with regard to condom use. It should be noted, however, that only a small proportion of the sample was sexually active and the use of contraceptives was accordingly found to be extremely low. The findings are discussed against the backdrop of the empirical literature on HIV/AIDS, developmental theory, and pertinent theories and models of health behaviour. This study may help to promote a better understanding of the psycho-educational dynamics of HIV infection in this special group of adolescents, and also help to inform attempts to tailor suitable educational programmes, as well as promote further research to add to our knowledge as we address the problems of HIV/AIDS among this group.

    Presented here is our methodology for developing automated aids for diagnosing faults in complex systems. We have designed these aids as multilevel-multiagent diagnostic aids based on principles that should be generally applicable to any complex system. In this methodology, ''multilevel'' refers to information models described at successful levels of abstraction that are tied together in such a way that reasoning is directed to the appropriate level as determined by the problem solving requirements. The concept of ''multiagent'' refers to the method of information processing within the multilevel model network; each model in the network is an independent information processor, i.e., an intelligent agent. 19 refs., 15 figs., 9 tabs

    The role of alcohol in the transmission of HIV and access to health services for persons living with HIV/AIDS is relatively unexamined across the globe. Our team’s community-based, mixed methods study examined both of these questions from the perspectives of Aboriginal persons living in Canada with HIV/AIDS (APHA) and service providers (SP). A bilingual national survey was undertaken with APHAs and SPs and the findings were followed up on in peer interviews. A complex relationship was identified between alcohol use, perceptions of alcohol use and access to services. Nearly half of APHAs surveyed reported that alcohol played a role in their becoming HIV positive. APHAs and SPs differed in their assessment of the impact of alcohol in the lives of Aboriginal persons once diagnosed, with a far greater proportion of SPs identifying it as problematic. Both SPs and APHAs associated the misuse of alcohol with diminished health. Nearly half of the APHAs surveyed shared they had been told they were drinking by a SP when they were not, while over one-third reported ever being denied services because of drinking when in fact they were not. Both SPs and APHAs identified physical health and discrimination as key reasons. Notwithstanding these results that point to shortcomings in service provision, the data also reveal that most APHAs are recieving care in which their choices are respected and from providers they trust. The findings point to the need for a nuanced strategy to solidify the strengths and address the shortcomings in APHA’s service provision. PMID:27867443

  17. Pedagogy of complex relationality exploring complexity theory, neuro-phenomenology, and attentiveness for education

    Science.gov (United States)

    Khattar, Randa

    What do the new sciences of complex relationality offer education? This work draws on complexity theory, neurological understandings of biology and phenomenology, and attentiveness to study what the new sciences might offer education and the possibilities of a pedagogical understanding of embodied knowing. Complexity theory provides understandings of local-global relationality, self-organization, far-from-equilibrium conditions, and emergent dynamics that are important for describing pedagogical relationality. In itself, however, complexity theory is lacking an attention to issues of embodiment that respond directly to an ethical understanding of relationality. Phenomenology provides important views on the human experience of perception, for example, Merleau-Ponty's, whose research opens up possibilities for embodiment and attentiveness. At the level of pedagogical practice, I will pose, following biologists Humberto Maturana and Francisco Varela's autopoietic self-making understanding of life, that attentiveness perspectives, which have been largely absent from western pedagogical theory and practice, are crucial to promoting embodied knowing for education. Maturana and Varela's autopoietic perspective offers an embodied understanding of living---and therefore education---which opens up necessary attentive spaces to listen to one another in non judgmental awareness in the present moment of experience. I offer insights into a relationally complex conception of education drawing on this biological and autopoietically-grounded framework. These insights are framed in the context of five clusters of relations: (1) emergence, far-from-equilibrium, and local-global relationality; (2) autopoietic autonomy, structural determination and sensory-motor coupling; (3) triggering perturbations, structural plasticity, and autopoietic organization; (4) knowing as adequate action, domains of interaction, and blind spots; and (5) attentiveness and responsive relationality.

  18. Using HIV&AIDS statistics in pre-service Mathematics Education to integrate HIV&AIDS education.

    2012-12-01

    In South Africa, the HIV&AIDS education policy documents indicate opportunities for integration across disciplines/subjects. There are different interpretations of integration/inclusion and mainstreaming HIV&AIDS education, and numerous levels of integration. Integration ensures that learners experience the disciplines/subjects as being linked and related, and integration is required to support and expand the learners' opportunities to attain skills, acquire knowledge and develop attitudes and values across the curriculum. This study makes use of self-study methodology where I, a teacher educator, aim to improve my practice through including HIV&AIDS statistics in Mathematics Education. This article focuses on how I used HIV&AIDS statistics to facilitate pre-service teacher reflection and introduce them to integration of HIV&AIDS education across the curriculum. After pre-service teachers were provided with HIV statistics, they drew a pie chart which graphically illustrated the situation and reflected on issues relating to HIV&AIDS. Three themes emerged from the analysis of their reflections. The themes relate to the need for further HIV&AIDS education, the changing pastoral role of teachers and the changing context of teaching. This information indicates that the use of statistics is an appropriate means of initiating the integration of HIV&AIDS education into the academic curriculum.

    First aid with cool running water reduces the severity of burn. Low level of knowledge of first aid in burns was shown in previous studies with few patients receiving first aid by water lavage. A study investigating the use of water lavage as first aid in patients presenting to hospital with burn in Lagos, Nigeria was carried out. Patients admitted to a University Teaching Hospital for treatment of burns were recruited for this prospective study. Data detailing demographics, scene and aetiology of burns, material used for first aid, who administered first aid, level of education and relationship of first-aider with patients, length of hospital stay, complications and outcome of treatment were collected and statistical analysis performed. 168 patients; 73 (43.4%) children and 95 (56.6%) adults were seen. Burns were sustained at home in 95 (74.2%) cases and outside in 33 (25.8%). Water lavage was used in 49 (29.2%) cases, raw eggs in 21 (12.5%), pap in 16 (9.5%) and other materials in 48.8%. 40 (23.8%) patients had not received any form of first aid at presentation. Patients that received no water first aid had higher complication rate (35.3% versus 18.4%) compared with those that had water first aid. The use of water first aid in burns was shown to reduce complication rate in this study. People should be educated on the efficacy of water first aid in pre-hospital care of burns.

    The prevalence of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) is higher among females than males in Sub-Saharan Africa. Education is associated with better health outcomes. For this and other reasons, African countries have made a concerted effort to increase youth education rates. However, in South Africa males have lower secondary education rates than females, yet females have a higher prevalence of HIV/AIDS. This study examines if a gender disparity exists in AIDS mortality rates among youth with secondary education in South Africa. This study uses descriptive statistics and life table techniques. A sample of 4386 deaths of youth with secondary education is used. Of this total sample, 987 deaths were among males and 340 were among females with secondary education. This study shows that AIDS mortality is higher among females than males in South Africa. Males and females with secondary education have lower AIDS mortality than all males and females in the population, yet the rates are higher for females. Using cause-deleted life tables, the probability of youth dying from HIV/AIDS practically disappears for both males and females. Odds ratio calculations show that secondary education does not have a protective effect from AIDS mortality among male and female youth. Given the gendered difference in AIDS mortality among youth with secondary education, efforts to increase secondary education among males and further research into other factors exacerbating AIDS mortality among females with secondary education is needed in the country.

  3. AIDS: the frightening facts.

    Ryan, M

    1986-01-01

    Aquired Immune Deficiency Syndrome (AIDS) has succeeded in creating an unprecedented wave of panic among the Western public and some sections of the medical profession. Research clearly shows that the AIDS virus is transmissible in a number of ways: from man to woman and vice versa during sexual intercourse, through semen and possibly vaginal fluids; from mothers to their children through breast milk; through exchange of saliva (but not through just a casual kiss); and through blood and blood products. Far from being exclusive to homosexuals, studies in Europe have shown that female virus carriers can transmit AIDS to healthy men through sexual intercourse--the predominant means by which transmission appears to occur in Central Africa. Although cases of AIDS began being diagnosed in a few Central African countries at the beginning of the 1980s, at the same time as they were first being observed in Europe and North America, many commentators assumed that the virus originated in Africa. Yet, it is safe to say that the nature of the virus, let alone its origins, remains controversial among scientists and virologists. 1 supporter of the theory that the AIDS virus has African origins is Robert Gall of the US National Institute of Health (NIH). He is one of the co-discoverers of the virus, which he named HTLV3 (Human T-cell Lymphotropic Virus 3). The virus also was discovered at France's Pasteur Institute by Luc Montaigner, who called it LAV (Lymphadenpathy Associated Virus). Gallo named the virus as he did because he believes it to be related to a pair of other viruses, HTLV1 and HTLV2, which like the AIDS virus attack the body's immunity system. Unlike AIDS, these 2 viruses, do not destroy the T-cells but cause them to replicate into cancer tumors. In Gallo's view, HTLV1 has long been endemic to some parts of Africa, from where he believes it spread via the slave trade to other parts of the world. Montaigner does not agree. He denies that the AIDS virus is related to

    Health-related quality of life (HRQoL) is increasingly recognized as an important outcome and as a complement to traditional biological end points of diseases such as mortality. Unless there is a complete cure available for HIV/AIDS, development and implementation of a reliable and valid cross cultural quality of life measure is necessary to assess not only the physical and medical needs of HIV/AIDS people, but their psychological, social, environmental, and spiritual areas of life. A qualitative exploration of HIV/AIDS patients' understanding, perceptions and expectations will be carried out with the help of semi structured interview guide by in depth interviews, while quantitative assessment of patient reported adverse drug reactions and their impact on health related quality of life will be carried out by using data collection tool comprising patient demographics, SF-12, Naranjo scale, and a clinical data sheet. The findings may serve as baseline QOL data of people living with HIV/AIDS in Malaysia and also a source data to aid construction of management plan to improve HIV/AIDS patients' QOL. It will also provide basic information about HIV/AIDS patients' perceptions, expectations and believes towards HIV/AIDS and its treatment which may help in designing strategies to enhance patients' awareness which in turn can help in addressing issues related to compliance and adherence. © 2013 John Wiley & Sons Ltd.

  5. AIDS: just the facts from specialists at Johns Hopkins.

    Finkbeiner, A

    1985-12-01

    This article, based on information from specialists at Johns Hopkins, poses and then answers 3 broad questions about the acquired immunodeficiency syndrome (AIDS). 1st, it is asked, "What is AIDS and how serious is it?" It is noted that AIDS is only 1 of several forms taken by infection with the human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). The earliest form of infection is believed to occur within a few weeks of exposure to the virus, and some patients develop an acute syndrome that resembles infectious mononucleosis. These symptoms disappear after 4-6 weeks, by which time the patient has developed antibodies to the virus. About 2-4%/year of asymptomatic carriers go on to develop AIDS-related complex (ARC), and 15-30% of ARC patients develop AIDS within 5 years. The 2nd question posed is, "How do you catch AIDS?" To cause infection, the virus must go directly into the blood, although the virus alone may not be enough to cause sickness. Previous viral infections such as hepatitis B, herpes, cytomegalovirus, and intestinal parasites have been suggested as co-factors of AIDS. Promiscuity increases the chances of contracting AIDS. Observations of the families of AIDS patients and health care personnel who work with AIDS patients suggest that AIDS cannot be caught by casual contact. Finally, it is asked, "What is being done about AIDS?" 4 strategies are outlined: 1) as a result of donor screening for antibodies to HTLV-III/LAV, AIDS has been completely removed from the blood banks; 2) virologists are attempting to understand the virus so that it can be attacked, and understanding has been advanced by the theory that HTLV-III might be what is called a "slow virus;" 3) education about AIDS is changing the sexual practices that transmit AIDS; and 4) epidemiologists are carefully following those who are at risk, have been exposed, or are already sick.

    Bystanders who are able to provide immediate first aid to patients who require emergency care can make a big difference in the outcome. Thus, first-aid training should be made available to as many people as possible. The aims of this study were to assess the level of first-aid knowledge among bystanders in emergency situations and to identify factors that affected this level of knowledge. At Dokuz Eylul University Emergency Service between February 1 and February 15, 2002, 318 bystanders were given a questionnaire. The first part of the questionnaire was concerned with demographic characteristics and factors that would affect first-aid knowledge level. The second part consisted of 16 multiple choice questions about first aid. Bystanders answered an average of 7.16+/-3.14 questions correctly. Bystanders who had graduated from a university, were health care personnel, had taken a first-aid course, had a first-aid certificate, or had a driver's license were considered to be more successful.

  7. Pseudo-complex general relativity

    Hess, Peter O; Greiner, Walter

    2016-01-01

    This volume presents an pseudo-complex extension of General Relativity which addresses these issues and presents proposals for experimental examinations in strong fields near a large mass. General Relativity is a beautiful and well tested theory of gravitation. Nevertheless, it implies conceptual problems like the creation of singularities (Black Holes) as a result of the collapse of large masses, or the appearance of event horizons which exclude parts of the space-time from the observation of external observers. The mathematical and geometrical foundations of this extension are displayed in detail, and applications including orbits and accretion disks around large central masses, neutron stars or cosmological models are introduced. Calculations both for classical and extended applications are often executed in the form of problems with extensive solutions, which makes this volume also a valuable resource for any student of General Relativity.

    Full Text Available Background: Being in its fourth decade, HIV remains an epidemic that requires combined efforts for the global fight. The strategies planned and implemented in the fight against HIV include reversing and halting the spread of HIV, increasing health care access, and strengthening the health care system. South Africa has made the fight one of its top priorities, and has developed plans to increase the role of nurses in the management of HIV, demonstrating its willingness, commitment and progress in the fight against HIV. Objective: This article presents the validation process conducted to confirm the integration and mapping of the HIV and AIDS related nursing competencies into the four-year Bachelor of Nursing programme at a university in South Africa. Methods: This study adopted a constructivist paradigm, using a qualitative approach, applyingthe design step of the process model of curriculum development, to validate the inte gration of the mapped HIV and AIDS related nursing competencies into the undergraduate nursing curriculum. Results: For each competency, outcomes were developed for each year. Participants confirmed completeness of outcomes and appropriateness of the mapping of the HIV and AIDS related outcomes into the nursing curriculum, as well as the feasibility and practicability of the integration. Conclusion: Required resources for integration of HIV and AIDS related nursing competencies, such as human resources and nurse educators’ continued personal development were identified, as well as barriers to integration, and measures to eliminate them were discussed. The importance of integration of HIV and AIDS nursing competencies into the curriculum was reiterated.

    With the advent of CAD/CAM and rapid prototyping (RP), a technical revolution in oral and maxillofacial trauma was promoted to benefit treatment, repair of maxillofacial fractures and reconstruction of maxillofacial defects. For a patient with zygomatico-facial collapse deformity resulting from a zygomatico-orbito-maxillary complex (ZOMC) fracture, CT scan data were processed by using Mimics 10.0 for three-dimensional (3D) reconstruction. The reduction design was aided by 3D virtual imaging and the 3D skull model was reproduced using the RP technique. In line with the design by Mimics, presurgery was performed on the 3D skull model and the semi-coronal incision was taken for reduction of ZOMC fracture, based on the outcome from the presurgery. Postoperative CT and images revealed significantly modified zygomatic collapse and zygomatic arch rise and well-modified facial symmetry. The CAD/CAM and RP technique is a relatively useful tool that can assist surgeons with reconstruction of the maxillofacial skeleton, especially in repairs of ZOMC fracture.

    No simple, noninvasive method is available for evaluating extracutaneous Kaposi sarcoma in AIDS patients or for following the tumor's response to treatment. We report our preliminary experience with thallium-201 scintigraphy in nine AIDS patients with proved Kaposi sarcoma. Eight of the nine had abnormal uptake of the radionuclide in skin, lymph nodes, oral cavity, vagina, and lungs. Only four of the nine had cutaneous Kaposi sarcoma at the time of scanning. All cutaneous and mucosal lesions were thallium avid. Two of the six patients with thallium-avid nodes underwent nodal biopsy. Both biopsies confirmed the diagnosis of Kaposi sarcoma. Cutaneous Kaposi sarcoma developed later in one of these patients, showing the efficacy of thallium scintigraphy for the early detection of extracutaneous lesions. These preliminary results show thallium avidity in Kaposi sarcoma involving the skin and various extracutaneous sites (lymph nodes, lung, mucosa, and vagina). Thallium scintigraphy is a potentially useful procedure for detecting extracutaneous Kaposi sarcoma in AIDS patients

    The aim of this study was to examine variation in the frequency of children's participation in out-of-school activities as a function of speech intelligibility, perceived effectiveness of the child's communication aid, and age. Sixty-nine caregivers of children with complex communication needs provided with communication aids completed a questionnaire survey. Rate of participation was higher for younger than for older children, particularly in recreational activities. Younger children with partial intelligibility participated more frequently in recreational and social activities than both younger children without speech and older children. Results and limitations are discussed within the context of participation research in childhood disability, highlighting the impact of communicative resources and maturation on everyday participation.

    Andrew J. Hughes

    2017-01-01

    Full Text Available Revision hip arthroplasty requires comprehensive appreciation of abnormal bony anatomy. Advances in radiology and manufacturing technology have made three-dimensional (3D representation of osseous anatomy obtainable, which provide visual and tactile feedback. Such life-size 3D models were manufactured from computed tomography scans of three hip joints in two patients. The first patient had undergone multiple previous hip arthroplasties for bilateral hip infections, resulting in right-sided pelvic discontinuity and a severe left-sided posterosuperior acetabular deficiency. The second patient had a first-stage revision for infection and recurrent dislocations. Specific metal reduction protocols were used to reduce artefact. The images were imported into Materialise MIMICS 14.12®. The models were manufactured using selective laser sintering. Accurate templating was performed preoperatively. Acetabular cup, augment, buttress, and cage sizes were trialled using the models, before being adjusted, and resterilised, enhancing the preoperative decision-making process. Screw trajectory simulation was carried out, reducing the risk of neurovascular injury. With 3D printing technology, complex pelvic deformities were better evaluated and treated with improved precision. Life-size models allowed accurate surgical simulation, thus improving anatomical appreciation and preoperative planning. The accuracy and cost-effectiveness of the technique should prove invaluable as a tool to aid clinical practice.

    Self-transcendence is a process that can help individuals reestablish well-being after experiencing a significant, life-altering event. In this study, we sought to identify the relationship between self-transcendence and depression in individuals who lost loved ones to HIV/AIDS and to describe and compare self-transcendence, self-transcendence variables of acceptance and spirituality, and depression among bereaved individuals who created AIDS Memorial Quilt panels with those who did not. The findings support Reed's self-transcendence theory, with inverse correlations between self-transcendence and depression obtained from both the total group and the panel makers. Significant differences were also found between certain self-transcendence variables and depression among the study participants related to gender and ethnicity. In addition, thematic analysis of panel maker interviews revealed five themes: Quilt panel making provides validation, Quilt panel making creates a living memory, liberating acceptance of loss, community of survivors, and connection to a higher power. These findings assist in understanding the complexities of the grief process and support the usefulness of Quilt panel making as an intervention for coping with grief related to HIV/AIDS.

    Full Text Available Aim: This study was aimed at assessing dispositions, attitudes, and behavioral tendencies for HIV/AIDS-related stigma and discrimination among health-care providers in Specialist Hospital Gombe, Northern Nigeria. Materials and Methods: Out of a total of 397 health personnel of the hospital, a sample of 201 health-care providers of various professional backgrounds was drawn using quota sampling technique. A descriptive exploratory survey method was adopted. Using a structured questionnaire, relevant data were collected from the subjects. Reliability test on key segments of the instrument yielded alpha Cronbach's internal consistency test values of not 0.05. If given the choice, 34 (16.9% of the personnel would not treat a patient with HIV. Conclusion: A prevalence rate of HIV/AIDS-related stigma of 15.4% among the health personnel is quite worrisome. Stigma reduction seminars and workshops would go a long way toward mitigating this trend.

    We investigate the super-de Rham complex of five-dimensional superforms with N=1 supersymmetry. By introducing a free supercommutative algebra of auxiliary variables, we show that this complex is equivalent to the Chevalley-Eilenberg complex of the translation supergroup with values in superfields. Each cocycle of this complex is defined by a Lorentz- and iso-spin-irreducible superfield subject to a set of constraints. Restricting to constant coefficients results in a subcomplex in which components of the cocycles are coboundaries while the constraints on the defining superfields span the cohomology. This reduces the computation of all of the superspace Bianchi identities to a single linear algebra problem the solution of which implies new features not present in the standard four-dimensional, N=1 complex. These include splitting/joining in the complex and the existence of cocycles that do not correspond to irreducible supermultiplets of closed differential forms. Interpreting the five-dimensional de Rham complex as arising from dimensional reduction from the six-dimensional complex, we find a second five-dimensional complex associated to the relative de Rham complex of the embedding of the latter in the former. This gives rise to a second source of closed differential forms previously attributed to the phenomenon called “Weyl triviality”.

    Full text: Aids patients are liable to more than one medical problem at anyone time as the number of CD4 cells decrease and the viral load increases. Problems are related to multiple causes of opportunistic Infections, malignant lymphoma and Kaposi sarcoma. Laboratory tests, sputum analysis and bronchial lavage have problems of decreased sensitivity. morphologic Imaging modalities such as chest X-ray, CT or MRI has problems of specificity. Nuclear medicine techniques has the advantage of total body functional imaging that can visualize more than one organ. The use nuclear medicine imaging is recommended when the diagnosis is uncertain and for initiation of proper treatment. Gallium-67 citrate total body scans acquired at 4 hours following the IV injection and at 24-48 hours has been very useful for the early diagnosis of opportunistic infections such as PCP, TB, Disseminated Mycobacterium avii complex; MAI, malignant lymphoma and various forms of AIDS related colitis. Sequential thallium and gallium scan help to differentiate Kaposi sarcoma (thallium positive, gallium negative) from opportunistic infections (gallium positive, thallium negative) and malignant lymphoma (thallium and gallium positive). Gallium is the most convenient radiopharmaceutical for the diagnosis of malignant lymphoma of the heart. Thallium and Tc-99m Sestamibi are useful for the differentiation of intracranial toxoplasmosis from malignant lymphoma. The presentation will illustrate different examples and will explain the limitations of all these tests. (author)

The methodology of the study was descriptive and quantitative descriptiveanalysis. The results of this study have said that older people have knowledge about HIV / AIDS. Only 22.2% use condoms. We conclude that prevention campaigns are not reaching the elderly. For we know that many seniors have active sex life, with more than one partner. Prevention campaigns and actions of the nursing staff should pay special attention to this fact and increase the information, so that older people can understand and adhere to the means of prevention of this disease.

    Full Text Available In this study, we investigated the relation between the use of hearing aids at the initial stages of hearing loss and age-related changes in the auditory and cognitive abilities of elderly persons. 12 healthy elderly persons participated in an annual auditory and cognitive longitudinal examination for three years. According to their hearing level, they were divided into 3 subgroups - the normal hearing group, the hearing loss without hearing aids group, and the hearing loss with hearing aids group. All the subjects underwent 4 tests: pure-tone audiometry, syllable intelligibility test, dichotic listening test (DLT, and Wechsler Adult Intelligence Scale-Revised (WAIS-R Short Forms. Comparison between the 3 groups revealed that the hearing loss without hearing aids group showed the lowest scores for the performance tasks, in contrast to the hearing level and intelligibility results. The other groups showed no significant difference in the WAIS-R subtests. This result indicates that prescription of a hearing aid during the early stages of hearing loss is related to the retention of cognitive abilities in such elderly people. However, there were no statistical significant correlations between the auditory and cognitive tasks.

    We assessed HIV/AIDS expenditures in Dehong Prefecture, Yunnan Province, one of the highest prevalence regions in China, and describe funding sources and spending for different categories of HIV-related interventions and at-risk populations. 2010 HIV/AIDS expenditures in Dehong Prefecture were evaluated based on UNAIDS' National AIDS Spending Assessment methodology. Nearly 93% of total expenditures for HIV/AIDS was contributed by public sources. Of total expenditures, 52.7% was allocated to treatment and care, 24.5% to program management and administration and 19.8% to prevention. Spending on treatment and care was primarily allocated to the treatment of opportunistic infections. Most (40.4%) prevention spending was concentrated on most-at-risk populations, injection drug users (IDUs), sex workers, and men who have sex with men (MSM), with 5.5% allocated to voluntary counseling and testing. Prevention funding allocated for MSM, partners of people living with HIV and prisoners and other confined populations was low compared to the disproportionate burden of HIV/AIDS in these populations. Overall, people living with HIV accounted for 57.57% of total expenditures, while most-at-risk populations accounted for only 7.99%. Our study demonstrated the applicability of NASA for tracking and assessing HIV expenditure in the context of China, it proved to be a useful tool in understanding national HIV/AIDS response from financial aspect, and to assess the extent to which HIV expenditure matches epidemic patterns. Limited funding for primary prevention and prevention for MSM, prisoners and partners of people living with HIV, signal that resource allocation to these key areas must be strengthened. Comprehensive analyses of regional and national funding strategies are needed to inform more equitable, effective and cost-effective HIV/AIDS resource allocation.

    Full Text Available We assessed HIV/AIDS expenditures in Dehong Prefecture, Yunnan Province, one of the highest prevalence regions in China, and describe funding sources and spending for different categories of HIV-related interventions and at-risk populations.2010 HIV/AIDS expenditures in Dehong Prefecture were evaluated based on UNAIDS' National AIDS Spending Assessment methodology.Nearly 93% of total expenditures for HIV/AIDS was contributed by public sources. Of total expenditures, 52.7% was allocated to treatment and care, 24.5% to program management and administration and 19.8% to prevention. Spending on treatment and care was primarily allocated to the treatment of opportunistic infections. Most (40.4% prevention spending was concentrated on most-at-risk populations, injection drug users (IDUs, sex workers, and men who have sex with men (MSM, with 5.5% allocated to voluntary counseling and testing. Prevention funding allocated for MSM, partners of people living with HIV and prisoners and other confined populations was low compared to the disproportionate burden of HIV/AIDS in these populations. Overall, people living with HIV accounted for 57.57% of total expenditures, while most-at-risk populations accounted for only 7.99%.Our study demonstrated the applicability of NASA for tracking and assessing HIV expenditure in the context of China, it proved to be a useful tool in understanding national HIV/AIDS response from financial aspect, and to assess the extent to which HIV expenditure matches epidemic patterns. Limited funding for primary prevention and prevention for MSM, prisoners and partners of people living with HIV, signal that resource allocation to these key areas must be strengthened. Comprehensive analyses of regional and national funding strategies are needed to inform more equitable, effective and cost-effective HIV/AIDS resource allocation.

    Activation-induced cytidine deaminase (AID) is essential for the somatic hypermutation (SHM) and class-switch recombination (CSR) of Ig genes. Although both the N and C termini of AID have unique functions in DNA cleavage and recombination, respectively, during SHM and CSR, their molecular mechanisms are poorly understood. Using a bimolecular fluorescence complementation (BiFC) assay combined with glycerol gradient fractionation, we revealed that the AID C terminus is required for a stable dimer formation. Furthermore, AID monomers and dimers form complexes with distinct heterogeneous nuclear ribonucleoproteins (hnRNPs). AID monomers associate with DNA cleavage cofactor hnRNP K whereas AID dimers associate with recombination cofactors hnRNP L, hnRNP U, and Serpine mRNA-binding protein 1. All of these AID/ribonucleoprotein associations are RNA-dependent. We propose that AID's structure-specific cofactor complex formations differentially contribute to its DNA-cleavage and recombination functions.

    In this paper, using E. Cartan's exterior calculus, we give the spinor form of the structure equations, which leads naturally to the Newman--Penrose equations. Furthermore, starting from the spinor spaces and the el (2C) algebra, we construct the general complex-vector formalism of general relativity. We find that both the Cahen--Debever--Defrise complex-vector formalism and that of Brans are its special cases. Thus, the spinor formalism and the complex-vector formalism of general relativity are unified on the basis of the uni-modular group SL(2C) and its Lie algebra

    Full Text Available Background: Approximately 35 new HIV (Human Immunodeficiency Virus, HIV cases and at least 1000 serious infections are transmitted annually to health care workers. In China, HIV prevalence is increasing and nursing personnel are encountering these individuals more than in the past. Contaminated needle-stick injuries represent a significant occupational burden for nurses. Evidence suggests that nurses in China may not fully understand HIV/AIDS (Acquired immunodeficiency syndrome, AIDS and HIV-related occupational safety. At this time, universal protection precautions are not strictly implemented in Chinese hospitals. Lack of training may place nurses at risk for occupational exposure to blood-borne pathogens. Objectives: To assess the effectiveness of integrated interventions on nurses’ knowledge improvement about reducing the risk of occupationally acquired HIV infection. Methods: We audited integrated interventions using 300 questionnaires collected from nurses at the Affiliated Hospital of Xiangnan University, a public polyclinic in Hunan Province. The intervention studied was multifaceted and included appropriate and targeted training content for hospital, department and individual levels. After three months of occupational safety integrated interventions, 234 participants who completed the program were assessed. Results: Of the subjects studied, 94.3% (283/300 were injured one or more times by medical sharp instruments or splashed by body fluids in the last year and 95.3% considered their risk of occupational exposure high or very high. After the intervention, awareness of HIV/AIDS-related knowledge improved significantly (χ2 = 86.34, p = 0.00, and correct answers increased from 67.9% to 82.34%. Correct answers regarding risk perception were significantly different between pre-test (54.4% and post-test (66.6% (χ2 = 73.2, p = 0.00. When coming into contact with patient body fluids and blood only 24.0% of subjects used gloves regularly

    Hollow nanostructures offer promising potential for advanced energy storage and conversion applications. In the past decade, considerable research efforts have been devoted to the design and synthesis of hollow nanostructures with high complexity by manipulating their geometric morphology, chemical composition, and building block and interior architecture to boost their electrochemical performance, fulfilling the increasing global demand for renewable and sustainable energy sources. In this Review, we present a comprehensive overview of the synthesis and energy-related applications of complex hollow nanostructures. After a brief classification, the design and synthesis of complex hollow nanostructures are described in detail, which include hierarchical hollow spheres, hierarchical tubular structures, hollow polyhedra, and multi-shelled hollow structures, as well as their hybrids with nanocarbon materials. Thereafter, we discuss their niche applications as electrode materials for lithium-ion batteries and hybrid supercapacitors, sulfur hosts for lithium-sulfur batteries, and electrocatalysts for oxygen- and hydrogen-involving energy conversion reactions. The potential superiorities of complex hollow nanostructures for these applications are particularly highlighted. Finally, we conclude this Review with urgent challenges and further research directions of complex hollow nanostructures for energy-related applications. © 2017 WILEY-VCH Verlag GmbH & Co.

    The prime purpose of this study is to assess HIV/AIDS-related self-stigma and discrimination (S&D) attitudes and associated factors using multivariate analysis of data from the 2010-11 National Survey of Understanding the Root of HIV/AIDS Related Stigma and Discrimination. A national telephone survey was carried out with 2271 of the Malaysian public aged 18-60 years. The sample was contacted by random digit dialing covering the whole of Peninsular Malaysia from December 2010 to May 2011. The HIV-transmission knowledge, HIV-related self-stigma, and public stigma were investigated. Despite high level of HIV-transmission knowledge [mean (SD)=10.56 (2.42), mean score at 70th percentile] the respondents in this study had moderate levels (mean scores near midpoints) of self-stigma and public stigma attitudes. HIV-transmission knowledge score was not significantly correlated with self-stigma score, but showed a significantly small positive effect (r<0.2) for public stigma scores. Ethnicity is the strongest correlate of HIV-transmission knowledge, self-stigma, and public stigma attitudes in the multivariate analyses. Other significant correlates were age, socioeconomic group, and urban-rural setting. The root causes of HIV stigma and discriminatory attitudes were not associated with knowledge deficiency. Interventions should be oriented towards promoting de-stigmatization of HIV/AIDS, and tailored socio-culturally. Copyright © 2013 Elsevier Inc. All rights reserved.

    Background The epidemic of HIV continues to grow in Nigeria. Personnel in the military are at increased risk of HIV infection. Although HIV-risk related sexual behavior of Nigerian police officers has been studied, little is known about the sexual behavior of their counterparts in the Navy. This study describes knowledge of AIDS, and HIV-risk sexual behavior of naval personnel in Lagos Nigeria. Methods Four hundred and eighty personnel of the Nigerian Navy completed a 70-item questionnaire in 2002. Group discussion and in-depth interviews of four key informants were also conducted to gain insights into the context of risky sexual behaviors and suggestions for feasible HIV primary prevention interventions. Results The mean age of the respondents was 34 years. Although the overall mean AIDS knowledge score was 7.1 of 10 points, 52.1% of respondents believed that a cure for AIDS was available in Nigeria and that one can get HIV by sharing personal items with an infected person (25.3%). The majority (88.1%) had had lifetime multiple partners ranging from 1–40 with a mean of 5.1; 32.5% of male respondents had had sexual contact with a female sex worker, 19.9% did so during the six months preceding the survey. Forty-one percent of those with sexual contact with a female sex worker did not use a condom during the most recent sexual encounter with these women. Naval personnel who have been transferred abroad reported significantly more risky sexual behaviors than others. Group discussants and key informants believed that sex with multiple partners is a tradition that has persisted in the navy even in the era of AIDS because of the belief that AIDS affects only foreigners, that use of traditional medicine provides protection against HIV infection, and influence of alcohol. Conclusion Many naval personnel report participating in high-risk sexual behavior which may increase their risk of acquiring and spreading HIV. Naval personnel live and interact freely with civilian

    Most of the treatment head components of medical linear accelerators used in radiation therapy have complex geometrical shapes. They are typically designed using computer-aided design (CAD) applications. In Monte Carlo simulations of radiotherapy beam transport through the treatment head components, the relevant beam-generating and beam-modifying devices are inserted in the simulation toolkit using geometrical approximations of these components. Depending on their complexity, such approximations may introduce errors that can be propagated throughout the simulation. This drawback can be minimized by exporting a more precise geometry of the linac components from CAD and importing it into the Monte Carlo simulation environment. We present a technique that links three-dimensional CAD drawings of the treatment head components to Geant4 Monte Carlo simulations of dose deposition. (note)

  6. State aid in the EU law and national law

    2011-01-01

    Full Text Available Due to emphasized negative implications, state aid in contemporary law is more and more the subject of legal rules of supra-national and international law, and consequently it is more and more frequently the subject of national laws. The systems of state aid are based on the principle of general non-allowedness of state aid, which is relativised with wide exceptions and the form of allowed and conditionally allowed forms of state aid. In the EU law, a complex and differentiated system of legal regime on state aid is created aimed at preventing the Member States to protect or promote their companies at the expense or harm of competition within the EU. Compared to the regulations that refer to subsidies and that are created at the international level, within the WTO, these regulations are much more detailed and they cover a wide spectrum of different forms of state aid. National laws are accepting the EU concept as a novelty, which is valid in particular for countries in the process of the EU integrations. This has been done in our law as well by enacting of the Law on state aid control. This Law regulates general conditions for granting, granting control, and utilization of state assistance, with the essential objective to establish and provide for competitive market conditions and introduction of order in the field that has not been regulated previously. At the same time, this means a successful fulfillment of the obligations related to pre-accession harmonization of this field, which is a necessary pre-condition for accession of our country into this group of countries since the EU standards and requirements have been fully observed with the above-mentioned Law.

    The present study aimed to investigate the changing relationship between aided speech recognition and cognitive function during the first 6 months of hearing aid use. Twenty-seven first-time hearing aid users with symmetrical mild to moderate sensorineural hearing loss were recruited. Aided speech recognition thresholds in noise were obtained in the hearing aid fitting session as well as at 3 and 6 months postfitting. Cognitive abilities were assessed using a reading span test, which is a measure of working memory capacity, and a cognitive test battery. Results showed a significant correlation between reading span and speech reception threshold during the hearing aid fitting session. This relation was significantly weakened over the first 6 months of hearing aid use. Multiple regression analysis showed that reading span was the main predictor of speech recognition thresholds in noise when hearing aids were first fitted, but that the pure-tone average hearing threshold was the main predictor 6 months later. One way of explaining the results is that working memory capacity plays a more important role in speech recognition in noise initially rather than after 6 months of use. We propose that new hearing aid users engage working memory capacity to recognize unfamiliar processed speech signals because the phonological form of these signals cannot be automatically matched to phonological representations in long-term memory. As familiarization proceeds, the mismatch effect is alleviated, and the engagement of working memory capacity is reduced. © The Author(s) 2014.

    We evaluated implementation of the British Columbia AIDS Information Line during its initial 15 weeks of operation. Data collected during daily operation of the line included call frequency, caller characteristics, response patterns, caller concerns and community referrals. Information on activities and resources required to implement the AIDS Line was also assembled. The study concluded that the advertising campaign sponsored by the provincial government and other AIDS-related media events had a strong impact on the frequency of calls made to the AIDS Line. However, the effect of both advertising and media events was of relatively short duration, suggesting that utilization of an AIDS information line is dependent on continuing promotional activities. The evaluation results demonstrate the importance of continuous collection of data online utilization, to track public awareness of and response to AIDS-related issues, and to facilitate planning of public education.

  12. Environmental influences on neural systems of relational complexity

    Full Text Available Constructivist learning theory contends that we construct knowledge by experience and that environmental context influences learning. To explore this principle, we examined the cognitive process relational complexity (RC, defined as the number of visual dimensions considered during problem solving on a matrix reasoning task and a well-documented measure of mature reasoning capacity. We sought to determine how the visual environment influences RC by examining the influence of color and visual contrast on RC in a neuroimaging task. To specify the contributions of sensory demand and relational integration to reasoning, our participants performed a non-verbal matrix task comprised of color, no-color line, or black-white visual contrast conditions parametrically varied by complexity (relations 0, 1, 2. The use of matrix reasoning is ecologically valid for its psychometric relevance and for its potential to link the processing of psychophysically specific visual properties with various levels of relational complexity during reasoning. The role of these elements is important because matrix tests assess intellectual aptitude based on these seemingly context-less exercises. This experiment is a first step toward examining the psychophysical underpinnings of performance on these types of problems. The importance of this is increased in light of recent evidence that intelligence can be linked to visual discrimination. We submit three main findings. First, color and black-white visual contrast add demand at a basic sensory level, but contributions from color and from black-white visual contrast are dissociable in cortex such that color engages a reasoning heuristic and black-white visual contrast engages a sensory heuristic. Second, color supports contextual sense-making by boosting salience resulting in faster problem solving. Lastly, when visual complexity reaches 2-relations, color and visual contrast relinquish salience to other dimensions of problem

    Full Text Available In economically developed countries, AIDS-related lymphoma (ARL accounts for a large proportion of malignances in HIV-infected individuals. Since the introduction of highly active anti-retroviral therapy (HAART in 1996, epidemiology and prognosis of ARL have changed. While there is a slight increase in the incidence of Hodgkin’s lymphoma in HIV-infected individuals, use of HAART has contributed to a decline in the incidence of non-Hodgkin’s lymphoma (NHL and also a decrease in the overall incidence of ARL. Strategies that employ HAART, improved supportive care, and the use of Rituximab with multi-agent chemotherapy have contributed to improved rates of complete remission and survival of patients with ARL that rival those seen in stage and histology matched HIV negative NHL patients. Most recent clinical trials demonstrate better outcomes with the use of rituximab in ARL. Tumor histogenesis (germinal center vs. non-germinal center origin is associated with lymphoma-specific outcomes in the setting of AIDS-related diffuse-large B cell lymphoma. High-dose chemotherapy (HDCT and autologous stem cell rescue (ASCT can be effective for a subset of patients with relapsed ARL. HIV sero-status alone should not preclude consideration of ASCT in the setting of ARL relapse. Clinical trials investigating the role of allogeneic hematopoietic stem cell transplant in ARL are currently underway.

    For the medical diagnostic imaging specialist in general, and for the nuclear medicine physician specifically, the AIDS epidemic has generated an enormous demand to develop a means of making early diagnoses of the complications of AIDS. For the most part this has meant the early detection, and when possible, the characterization of the opportunistic infections and neoplasms that are a major source of morbidity and mortality for the AIDS patient. Detection of opportunistic infections has been helpful in reclassifying HIV-seropositive patients as having AIDS. This paper reports on nuclear medicine used to evaluate the efficacy and the complications of treatment in human immunodeficiency virus infection. Most recently, functional brain imaging has been used for the diagnosis and follow-up of the AIDS dementia complex

    The study aimed (a) to profile audiologists' language during the diagnosis and management planning phase of hearing assessment appointments and (b) to explore associations between audiologists' language and patients' decisions to obtain hearing aids. Sixty-two audiologist-patient dyads participated. Patient participants were aged 55 years or older. Hearing assessment appointments were audiovisually recorded and transcribed for analysis. Audiologists' language was profiled using two measures: general language complexity and use of jargon. A binomial, multivariate logistic regression analysis was conducted to investigate the associations between these language measures and hearing aid uptake. The logistic regression model revealed that the Flesch-Kincaid reading grade level of audiologists' language was significantly associated with hearing aid uptake. Patients were less likely to obtain hearing aids when audiologists' language was at a higher reading grade level. No associations were found between audiologists' use of jargon and hearing aid uptake. Audiologists' use of complex language may present a barrier for patients to understand hearing rehabilitation recommendations. Reduced understanding may limit patient participation in the decision-making process and result in patients being less willing to trial hearing aids. Clear, concise language is recommended to facilitate shared decision making.

    The aim of this study was to investigate parent-reported challenges related to hearing aid management and parental psychosocial characteristics during the first 3 years of the child's life. Using a cross-sectional survey design, surveys were distributed to parents of children with hearing loss via state Early Intervention programs in Utah and Indiana. Packets contained one family demographic form and two sets of three questionnaires to obtain responses from mothers and fathers separately: the Parent Hearing Aid Management Inventory explored parent access to information, parent confidence in performing skills, expectations, communication with the audiologist, and hearing aid use challenges. The Acceptance and Action Questionnaire measured psychological flexibility, experiential avoidance, and internal thought processes that can affect problem-solving ability and decrease an individual's ability to take value-based actions. The Patient Health Questionnaire identified symptoms of depression. Thirty-seven families completed questionnaires (35 mothers and 20 fathers). Most responses were parents of toddlers (M = 22 months) who had been wearing binaural hearing aids for an average of 15 months. Both mothers and fathers reported that even though the amount of information they received was overwhelming, most (84%) preferred to have all the information at the beginning, rather than to receive it over an extended time period. Parents reported an array of challenges related to hearing aid management, with the majority related to daily management, hearing aid use, and emotional adjustment. Sixty-six percent of parents reported an audiologist taught them how to complete a listening check using a stethoscope, however, only one-third reported doing a daily hearing aid listening check. Both mothers and fathers reported a wide range of variability in their confidence in performing activities related to hearing aid management, and most reported minimal confidence in their ability to

    The Indian Health Organization projected the number of deaths per day due to AIDS by the year 2000 at 10,000. An interdisciplinary international conference was held in New Delhi to draft an international law governing the issues related to AIDS. Human freedom and public health policies are the most affected by this disease. In the absence of an international AIDS law, judicial verdicts set precedents and could have serious ramifications. A participant from the John Marshall Law School, Chicago, suggested that instead of making new laws, the existing ones from the colonial past should be repealed. This includes Section 377 of the Indian Penal Code, which provides criminal sanctions against those who indulge in unnatural relations with man, woman, or animal. Penalizing homosexuality will only perpetuate clandestine relations and spread the virus into their families. Another participant seconded this motion stating that even a sex worker must be protected from abuse and indignity. The National AIDS Control Organization responded to the criticism that the government had not utilized all the World Bank funds allocated for anti-AIDS projects. The trends of the epidemic were the most important indicators not just the numbers. In Manipur and Mizoram, infection was almost entirely due to injecting drug use. The Saheli project undertaken in the red-light areas of Bombay encompassed brothel owners and prostitutes, which could be replicated in other areas. Because existing government policies were focusing on prevention, there was no protection of an HIV-infected individual's privacy, one participant from Madras stated. The confidentiality issue was also echoed by a US participant. The New Delhi Declaration and Action Plan on HIV/AIDS was also discussed. It forbids discrimination in employment, education, housing, health care, social security, travel, and marital and reproductive rights. Providing sterile needles and ensuring the safety of the blood supply were other concerns

  1. A situation-response model for intelligent pilot aiding

    1987-01-01

    An intelligent pilot aiding system needs models of the pilot information processing to provide the computational basis for successful cooperation between the pilot and the aiding system. By combining artificial intelligence concepts with the human information processing model of Rasmussen, an abstraction hierarchy of states of knowledge, processing functions, and shortcuts are developed, which is useful for characterizing the information processing both of the pilot and of the aiding system. This approach is used in the conceptual design of a real time intelligent aiding system for flight crews of transport aircraft. One promising result was the tentative identification of a particular class of information processing shortcuts, from situation characterizations to appropriate responses, as the most important reliable pathway for dealing with complex time critical situations.

    Full Text Available Background and Aim: Hearing loss is one of the most prevalent chronic diseases in the elderly; using a hearing aid to alleviate auditory impairment can positively affect their quality of life. This research aimed to determine the level of satisfaction concerning hearing aids in elderly people with hearing impairment based on the type and degree of hearing loss.Methods: An analytic cross-sectional research design was used ; the sample included 40 elderly people who used hearing aids. According to the World Health Organization (WHO age classification, participants were divided into two age groups: 65-74 years (n=20 and 75-90 years (n=20. Satisfaction levels were assessed using a standard satisfaction with amplification in daily life (SADL questionnaire.Results: Satisfaction levels in the 65-74 age group were significantly higher than that in the 75-90 age group (p=0.02. Participants with mixed hearing loss revealed higher satisfaction levels than participants with sensorineural hearing loss (p=0.02. On the negative effects dimension, participants with severe hearing loss exhibited significantly higher satisfaction levels than participants with moderate or moderate to severe hearing loss (p=0.01.Conclusion: Total satisfaction mean scores were relatively high in the elderly participants . Negative features could be reduced via careful consultation regarding the aids’ amplifying capabilities and limitations in groups with moderate or moderate to severe hearing loss.

    Full Text Available In this study, we propose a Bilateral Double Motive framework of stakeholder cooperation in complex projects. The framework analyses and explains dyadic promoter-stakeholder relationships at a micro level by acknowledging both transactional and relational motives. We demonstrate the framework’s usefulness by illustrating its explanatory power in two instances of cooperation and two of non-cooperation within two health information technology projects. The study contributes to project management theory through its combined focus on transactional and relational motives. Further, the study contributes to practice by providing a tool for planning and evaluating cooperation in health Information Technology projects and similar complex multi-stakeholder environments.

    2016-01-01

    How do people think about complex phenomena like the behavior of ecosystems? Here we hypothesize that people reason about such relational systems in part by creating spatial analogies, and we explore this possibility by examining spontaneous gestures. In two studies, participants read a written lesson describing positive and negative feedback systems and then explained the differences between them. Though the lesson was highly abstract and people were not instructed to gesture, people produced spatial gestures in abundance during their explanations. These gestures used space to represent simple abstract relations (e.g., increase ) and sometimes more complex relational structures (e.g., negative feedback ). Moreover, over the course of their explanations, participants' gestures often cohered into larger analogical models of relational structure. Importantly, the spatial ideas evident in the hands were largely unaccompanied by spatial words. Gesture thus suggests that spatial analogies are pervasive in complex relational reasoning, even when language does not.

    2007-02-01

    Full Text Available Abstract Background AIDS-related non-Hodgkin's lymphoma (AIDS-NHL is the second most frequent cancer associated with AIDS, and is a frequent cause of death in HIV-infected individuals. Experimental analysis of AIDS-NHL has been facilitated by the availability of an excellent animal model, i.e., simian Acquired Immunodeficiency Syndrome (SAIDS in the rhesus macaque consequent to infection with simian immunodeficiency virus. A recent study of SAIDS-NHL demonstrated a lymphoma-derived cell line to be sensitive to the growth inhibitory effects of the ubiquitous cytokine, transforming growth factor-beta (TGF-beta. The authors concluded that TGF-beta acts as a negative growth regulator of the lymphoma-derived cell line and, potentially, as an inhibitory factor in the regulatory network of AIDS-related lymphomagenesis. The present study was conducted to assess whether other SAIDS-NHL and AIDS-NHL cell lines are similarly sensitive to the growth inhibitory effects of TGF-beta, and to test the hypothesis that interleukin-6 (IL-6 may represent a counteracting positive influence in their growth regulation. Methods Growth stimulation or inhibition in response to cytokine treatment was quantified using trypan blue exclusion or colorimetric MTT assay. Intracellular flow cytometry was used to analyze the activation of signaling pathways and to examine the expression of anti-apoptotic proteins and distinguishing hallmarks of AIDS-NHL subclass. Apoptosis was quantified by flow cytometric analysis of cell populations with sub-G1 DNA content and by measuring activated caspase-3. Results Results confirmed the sensitivity of LCL8664, an immunoblastic SAIDS-NHL cell line, to TGF-beta1-mediated growth inhibition, and further demonstrated the partial rescue by simultaneous treatment with IL-6. IL-6 was shown to activate STAT3, even in the presence of TGF-beta1, and thereby to activate proliferative and anti-apoptotic pathways. By comparison, human AIDS-NHL cell lines

    Objective We use children's drawings to investigate social stigmatization of AIDS-affected and poverty-affected children by their peers, in the light of suggestions that the stigmatization of AIDS-affected children might derive more from the poverty experienced by these children than from their association with AIDS. Methods A qualitative study, in rural Zimbabwe, used draw-and-write techniques to elicit children's (10–12 years) representations of AIDS-affected children (n= 30) and poverty-affected children (n= 33) in 2009 and 2010 respectively. Results Representations of children affected by AIDS and by poverty differed significantly. The main problems facing AIDS-affected children were said to be the psychosocial humiliations of AIDS stigma and children's distress about sick relatives. Contrastingly, poverty-affected children were depicted as suffering from physical and material neglect and deprivation. Children affected by AIDS were described as caregivers of parents whom illness prevented from working. This translated into admiration and respect for children's active contribution to household survival. Poverty-affected children were often portrayed as more passive victims of their guardians' inability or unwillingness to work or to prioritize their children's needs, with these children having fewer opportunities to exercise agency in response to their plight. Conclusions The nature of children's stigmatization of their AIDS-affected peers may often be quite distinct from poverty stigma, in relation to the nature of suffering (primarily psychosocial and material respectively), the opportunities for agency offered by each affliction, and the opportunities each condition offers for affected children to earn the respect of their peers and community. We conclude that the particular nature of AIDS stigma offers greater opportunities for stigma reduction than poverty stigma. PMID:21985490

    1995-01-01

    For the medical diagnostic imaging specialist in general, and for the nuclear medicine physician specifically, the AIDS epidemic has generated an enormous demand to develop a means of making early diagnoses of the complications of AIDS. For the most part this has meant the early detection, and when possible, the characterization of the opportunistic infections and neoplasms that are a major source of morbidity and mortality for the AIDS patient. Detection of opportunistic infections has been helpful in reclassifying HIV-seropositive patients as having AIDS. This paper reports on nuclear medicine used to evaluate the efficacy and the complications of treatment in human immunodeficiency virus infection. Most recently, functional brain imaging has been used for the diagnosis and follow-up of the AIDS dementia complex. (author). 77 refs., 8 figs

    Full Text Available Chylous ascites is very rare in HIV/AIDS and its association with Mycobacterium avium complex-immune reconstitution inflammatory syndrome (MAC-IRIS has been rarely reported. Here, we report a case of a young African-American male who developed chylous ascites as a late sequela to immune reconstitution inflammatory syndrome while on treatment for MAC. Antiretroviral drug-naive patients who start HAART in close proximity to the diagnosis of an opportunistic infection and have a rapid decline in HIV RNA level should be monitored for development of IRIS. Although the long term prognosis is poor, early diagnosis and treatment help to improve quality of life.

    Full Text Available Abstract Background Information on the HIV and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS, and for attracting the attention of dental school educators towards the subject. Purposes Focusing on a census of dental students attending their 3rd, 4th and 5th study year at publicly – and privately funded dental faculties in Khartoum, this study aimed to assess the prevalence and socio-economic correlates of dental students' knowledge, sources of information and reported need for further education related to HIV and AIDS. Methods At the time of the survey (March–May 2007, the total number of dental students registered was 782 of which 642 (response rate 82%, mean age 21.7 year, 72% girls completed anonymous self-administered questionnaires in supervised class room settings. Results A total of 49% and 86% had correct sum scores with respect to knowledge of transmission through contamination and through shaking hands and eating, respectively. About half the dental students recognized a need for further education across HIV related issues, varying from 75% (basic HIV/AIDS related issues to 84% (patient management. Only 38% of the students had correct sum scores regarding various occupational groups at risk for contacting HIV and AIDS. Multiple logistic regression analysis revealed that compared to privately funded dental school students, publicly funded dental school students were less likely to have correct knowledge about modes of HIV transmission (OR = 0.6 and occupational risk groups (OR = 0.6 and to have received information from lectures/health care workers (OR = 0.5. Conclusion Students attending privately funded schools were more knowledgeable about various HIV related issues than students from publicly funded schools. About half of the students investigated had received HIV/AIDS information from various sources and reported need

    2008-11-15

    This article investigates the 2008 reform of the EU's environmental state aid guidelines, with an eye to determining the degree of external pressure and lobbyism towards environmental state aid policies. What is found is a strikingly low level of external pressure on the policy-field, not least on the part of the private sector. In fact, EU environmental state aid policy is largely the making of a few Commission officials, without much external 'interference'. The article discusses possible reasons for this, and asks whether state aid policy-making might be marked less by clear and established interests and utility maximising, and more by actors constrained by complexity and bounded rationality.

    The spectrum of training aids used in the nuclear industry runs the gamut from the very basic (i.e., valve training aids - gate, globe, check) to the highly complex (i.e., nuclear full scope simulator). Designing and purchasing the best training aids take much time, detailed investigation, and good understanding of plant operations. The training aid that has given the New York Power Authority the best results has been the motor operator valve (MOV) trainer. Some of the items that make the MOV trainer a good choice are: (1) large number of MOVs in the plant, (2) importance of MOVs to safe plant operation, (3) detailed MOV procedures used by the plant, (4) history of MOV problems, and (5) ability to demonstrate important concepts and operation - hammer blow effect, torque and limit switch adjustment and functions, and actual sequence of operation of the limitorque valve operator

    The present paper reports a continuation of investigations on the complexing ability of substituted polycarboxylate ligands toward the uranyl(VI) ion. The changes in free energy were computed from the stability constants determined by potentiometric measurements; the enthalpy changes were measured by direct calorimetric titrations. The acid formation constants and the complex formation constants were calculated with the aid of a CDC/CRYBER '76 computer using the programs LETAGROP VRID and MINIQUAD 75. The enthalpy changes for the proton ligand and metal ligand complex formation were calculated by the least-squares program LETAGROP KALLE. The data obtained for a relatively wide range of concentrations of the metal and hydrogen ions may be interpreted in terms of the formation of simple mononuclear, ML, and acid complexes, Msub(p)Hsub(q)Lsub(r), where p = 1; q = 1, 2; r = 1, 2. The values of free energy enthalpy, and entropy changes for the systems investigated are reported together with the logarithms of the corresponding stability constants. (author)

    Complex Trauma-related Disorders in Research and Practice Frequent traumata in childhood and adolescence are long-term or repeated interpersonal traumata caused by perpetrators in the close environment of the minors. For the description of the extensive symptoms after interpersonal Type II traumata, the complex trauma-related disorders Complex Posttraumatic Stress Disorder (CPTSD) or Disorder of Extreme Stress Not Otherwise Specified (DESNOS) and the Developmental Trauma Disorder (DTD) are being discussed for inclusion in the classification systems for mental disorders. Scientific knowledge and practical experiences regarding CPTSD, DESNOS and DTD in children and adolescents up to 18 years were examined by 1) a Systematic Review of 1,070 publications identified by database research and additional search strategies, and 2) a nationwide online survey of 374 psychotherapists and psychiatrists for children and adolescents in Germany. Of 13 included empirical studies (8 CPTSD or DESNOS, 5 DTD), 9 were conducted in the USA, 4 based on file coding and 3 on secondary data analysis and only 7 reported diagnosis rates (range: 0-78 %). Of the interviewed therapists, 100 % considered the CPTSD as being met with at least one patient with interpersonal traumata up to 18 years of age in 2014 and 99 % gave this estimate for the DTD. Two thirds of therapists rated the diagnostic option CPTSD and DTD as "very often" or "often" helpful for their therapeutic work with children and adolescents. While empirical data available is to be considered insufficient and characterized by methodological limitations, the relevance of complex trauma-related disorders is perceived as high by practitioners.

    The present study investigates behavioral and electrophysiological auditory and cognitive-related plasticity in three groups of healthy older adults (60-77 years). Group 1 was moderately hearing-impaired, experienced hearing aid users, and fitted with new hearing aids using non-linear frequency compression (NLFC on); Group 2, also moderately hearing-impaired, used the same type of hearing aids but NLFC was switched off during the entire period of study duration (NLFC off); Group 3 represented individuals with age-appropriate hearing (NHO) as controls, who were not different in IQ, gender, or age from Group 1 and 2. At five measurement time points (M1-M5) across three months, a series of active oddball tasks were administered while EEG was recorded. The stimuli comprised syllables consisting of naturally high-pitched fricatives (/sh/, /s/, and /f/), which are hard to distinguish for individuals with presbycusis. By applying a data-driven microstate approach to obtain global field power (GFP) as a measure of processing effort, the modulations of perceptual (P50, N1, P2) and cognitive-related (N2b, P3b) auditory evoked potentials were calculated and subsequently related to behavioral changes (accuracy and reaction time) across time. All groups improved their performance across time, but NHO showed consistently higher accuracy and faster reaction times than the hearing-impaired groups, especially under difficult conditions. Electrophysiological results complemented this finding by demonstrating longer latencies in the P50 and the N1 peak in hearing aid users. Furthermore, the GFP of cognitive-related evoked potentials decreased from M1 to M2 in the NHO group, while a comparable decrease in the hearing-impaired group was only evident at M5. After twelve weeks of hearing aid use of eight hours each day, we found a significantly lower GFP in the P3b of the group with NLFC on as compared to the group with NLFC off. These findings suggest higher processing effort, as

Eighty hundred and sixty-nine patients (351 female and 518 male) received radiographs of the hand for trauma and were screened for a host of conditions known to affect the joint spaces. All participants underwent measurements of joint space distances at the metacarpal-phalangeal articulation (JSD-MCP) from the thumb to the small finger and at the proximal-interphalangeal articulation (JSD-PIP) from the index finger to the small finger using computer-aided diagnosis technology with semi-automated edge detection. The study revealed an annual narrowing of the JSD of 0.6% for the JSD-MCP and for the JSD-PIP. Furthermore, the data demonstrated a notable age-related decrease in JSD, including an accentuated age-related joint space narrowing in women for both articulations. Additionally, males showed a significantly wider JSD-MCP (+11.1%) and JSD-PIP (+15.4%) compared with the female cohort in all age groups. Our data presented gender-specific and age-related normative reference values for computer-aided joint space analysis of the JSD-MCP and JSD-PIP that could be used to identify disease-related joint space narrowing, particularly in patients with osteoarthritis and rheumatoid arthritis commonly involving the peripheral small hand joints.

  7. AIDS: "it's the bacteria, stupid!".

    Acid-fast tuberculous mycobacterial infections are common in AIDS and are regarded as secondary "opportunistic infections." According to the National Institute of Allergy and Infectious Diseases, TB is the major attributable cause of death in AIDS patients. Could such bacteria play a primary or causative role in AIDS? Certainly, In screening tests for HIV, there is frequent, up to 70%, cross-reactivity, between the gag and pol proteins of HIV and patients with mycobacterial infections such as tuberculosis. By 1972, five years before gays started dying in the U.S., Rolland wrote Genital Tuberculosis, a Forgotten Disease? And ironically, in 1979, on the eve of AIDS recognition, Gondzik and Jasiewicz showed that even in the laboratory, genitally infected tubercular male guinea pigs could infect healthy females through their semen by an HIV-compatible ratio of 1 in 6 or 17%, prompting him to warn his patients that not only was tuberculosis a sexually transmitted disease, but also the necessity of the application of suitable contraceptives, such as condoms, to avoid it. Gondzik's solution and date of publication are chilling; his findings significant. Since 1982 Cantwell et al found acid-fast bacteria closely related to tuberculosis (TB) and atypical tuberculosis in AIDS tissue. On the other hand molecular biologist and virologist Duesberg, who originally defined retroviral ultrastructure, has made it clear that HIV is not the cause of AIDS and that the so-called AIDS retrovirus has never been isolated in its pure state. Dr. Etienne de Harven, first to examine retroviruses under the electron, agrees. In 1993 HIV co-discoverer Luc Montagnier reported on cell-wall-deficient (CWD) bacteria which he called "mycoplasma" in AIDS tissue. He suspected these as a necessary "co-factor" for AIDS. Remarkably, Montagnier remained silent on Cantwell's reports of acid-fast bacteria which could simulate "mycoplasma" in AIDS tissue. Mattman makes clear that the differentiation between

    Under international, regional, and domestic law, adolescents are entitled to measures ensuring the highest attainable standard of health. For HIV/AIDS, this is essential as adolescents lack many social and economic protections and are disproportionately vulnerable to the effects of the disease. In many countries, legal protections do not always ensure access to health care for adolescents, including for HIV/AIDS prevention, treatment, and care. Using Rwanda as an example, this article identifies gaps, policy barriers, and inconsistencies in legal protection that can create age-related barriers to HIV/AIDS services and care. One of the most pressing challenges is defining an age of majority for access to prevention measures, such as condoms, testing and treatment, and social support. Occasionally drawing on examples of existing and proposed laws in other African countries, Rwanda and other countries may strengthen their commitment to adolescents' rights and eliminate barriers to prevention, family planning, testing and disclosure, treatment, and support. Among the improvements, Rwanda and other countries must align its age of consent with the actual behavior of adolescents and ensure privacy to adolescents regarding family planning, HIV testing, disclosure, care, and treatment.

    . In this thesis, several challenges encountered in the process of modelling and optimizing hearing aids are addressed. Firstly, a strategy for modelling the contacts between plastic parts for harmonic analysis is developed. Irregularities in the contact surfaces, inherent to the manufacturing process of the parts....... Secondly, the applicability of Model Order Reduction (MOR) techniques to lower the computational complexity of hearing aid vibro-acoustic models is studied. For fine frequency response calculation and optimization, which require solving the numerical model repeatedly, a computational challenge...... is encountered due to the large number of Degrees of Freedom (DOFs) needed to represent the complexity of the hearing aid system accurately. In this context, several MOR techniques are discussed, and an adaptive reduction method for vibro-acoustic optimization problems is developed as a main contribution. Lastly...

    Full Text Available Objectives. To assess participants’ knowledge about HIV/AIDS and to identify the factors associated with HIV/AIDS in Sudan. Methods. Observational cross-sectional study carried out at Omdurman National Voluntary Counseling and Testing Centre, Sudan covered 870 participants. Sociodemographic data as well as information related to sexual behavior were collected. Results. Most of the respondents were knowledgeable about the true transmission modes for AIDS virus. Very few respondents knew someone infected with AIDS (4.5%, died of AIDS (8.1%, accepted to live with someone infected with AIDS (4.7% or to work with someone infected with AIDS (2.1%. Regarding sexual behavior, 96.5% had reported their first sexual experience between 20 and 30 years, with 85.7% reporting one or two partners, and only 1.8% reported using condom. Multivariate logistic regression showed that circumcision, religion, marital status, age at first sex, number of sexual partners, education level, and misconception of knowledge are the main risk factors associated with HIV/AIDS. Conclusion. Our results showed that a number of diversity risk factors were associated with HIV/AIDS. It is unlikely that a holistic approach will be found to immediately change sexual-risk-relating behavior. Interventions including sustained educational programs, promotion of condom, and encouragement of voluntary testing and active involvement of the country’s political and religious leaders will be needed to alleviate this problem.

    Accessories, such as end plates, deflecting plates, shielding and guide vanes, may increase the power of a Savonius rotor, but make the system structurally complex. In such cases, the rotor can develop a relatively large torque at small rotational speeds and is cheap to build, however it harnesses only a small fraction of the incident wind energy. Another proposition for increasing specific output is to place non-return valves inside the concave side of the blades. Such methods have been studied experimentally with a twisted-blade Thus improving a Savonius rotor's energy capture. This new concept has been named as the 'Valve-Aided Twisted Savonius'rotor. Tests were conducted in a low-speed wind tunnel to evaluate performance. This mechanism is found to be independent of flow direction, and shows potential for large machines. [Author].

    2009-01-01

    Models for diseases spreading are not just limited to SIS or SIR. For instance, for the spreading of AIDS/HIV, the susceptible individuals can be classified into different cases according to their immunity, and similarly, the infected individuals can be sorted into different classes according to their infectivity. Moreover, some diseases may develop through several stages. Many authors have shown that the individuals' relation can be viewed as a complex network. So in this paper, in order to better explain the dynamical behavior of epidemics, we consider different epidemic models on complex networks, and obtain the epidemic threshold for each case. Finally, we present numerical simulations for each case to verify our results.

    Work-related musculoskeletal disorders (WMSDs) have become increasingly common among health-related professionals. Special education personnel who serve students with disabilities often experience physical strains; however, WMSDs have been overlooked in this population. The objectives of this study were to investigate the work-related ergonomics-associated factors in this population and to evaluate their correlation with the WMSDs prevalence. A questionnaire with three domains, namely demographics, prevalence of work-related musculoskeletal disorders, and ergonomic factors, designed by our research team was delivered to educators who work in special education schools. Approximately 86 % of the 388 special education school teachers and teacher's aides in this study experienced musculoskeletal disorders. The lower back, shoulder, and wrist were the three most affected regions. A logistic regression analysis revealed that the participants' background factors, namely >5.5 years of experience (odds ratio [OR] = 4.090, 95 % CI: 1.350-12.390), students with multiple disorders (OR = 2.412, 95 % CI: 1.100-5.287), and other work-related ergonomic factors (assistance in diaper changing and others duties), were strongly associated with the prevalence of WMSD. Nap habit (OR = 0.442, 95 % CI: 0.230-0.851) and having teaching partners in the same class (OR = 0.486, 95 % CI: 0.250-0.945) resulted in low possibility of acquiring WMSDs. The use of supportive devices was associated with a low WMSD prevalence. The present study revealed an association between WMSDs and specific job features among teachers and teacher's aides in special education schools. Future efforts should emphasize examining safe student-handling ergonomics, formulating policies regarding student-teacher ratio, incorporating mandatory break times at the workplaces, and promoting personal health for preventing work-related injuries.

    2014-07-01

    Morality and empathy are fundamental components of human nature across cultures. However, the wealth of empirical findings from developmental, behavioral, and social neuroscience demonstrates a complex relation between morality and empathy. At times, empathy guides moral judgment, yet other times empathy can interfere with it. To better understand such relations, we propose abandoning the catchall term of empathy in favor of more precise concepts, such as emotional sharing, empathic concern, and affective perspective-taking.

    2010-06-01

    Full Text Available Abstract Background Although there are an increasing number of studies on HIV-related stigma in Nigeria, very little research has focused on how power differences based on gender perpetuate the stigmatization of people living with HIV/AIDS (PLWHA and how these gender differences affect the care that PLWHA receive in health care institutions. We explore gender-related beliefs and reactions of society, including health care professionals (HCPs, with regard to PLWHA, using Connell's theoretical framework of gender and power (1987. With Connell's structural theory of gender and power (financial inequality, authority and structure of social norms, we can describe gender differences in stigmatization of PLWHA. Method We conducted in-depth semi-structured interviews, lasting 60 to 90 minutes, with 100 persons (40 members of the general public, 40 HCPs and 20 PLWHA in Port Harcourt, Nigeria. The interviews were tape-recorded and transcribed verbatim. The Nvivo 7 computer package was used to analyze the data. Results There are similarities and differences between the general public and HCPs towards PLWHA in gender-related beliefs and reactions. For instance, although association with promiscuity and power differences were commonly acknowledged in the different groups, there are differences in how these reactions are shown; such as HCPs asking the female PLWHA to inform their partners to ensure payment of hospital bills. Women with HIV/AIDS in particular are therefore in a disadvantaged position with regard to the care they receive. Conclusion Despite the fact that men and women with HIV/AIDS suffer the same illness, clear disparities are apparent in the negative reaction women and men living with HIV/AIDS experience in society. We show that women's generally low status in society contributes to the extreme negative reactions to which female PLWHA are subject. The government should create policies aimed at reducing the power differences in family, society

    This study aimed to review knowledge, attitudes and practices related to sexual transmitted diseases (STD) and HIV/AIDS among men who have sex with men (MSM) in Senegal. The study was undertaken from February 1st to June 30th 2007, in three capitals cities in Senegal (one national, and two regional). It concerned the MSM that benefited from at least one of services of an MSM association. Studied variables included socio demographic characteristics, sexual practices, as well as knowledge and attitudes related to STDs and VIH/AIDS. Interviews took place during appointments obtained by direct phone call or by two MSM leaders intermediary. Data were seized and analyzed with Epi2000 Software. Among 245 registered MSM, 63 had a precise contact (address and/or phone number), and 49 aged in average of 25 years were investigated. Among them, one was illiterate, five studied Koran, seven Arab and 36 French. The socio-professional categories differentiated two officials, two merchants, one mechanic, one fighter, five artists, five restorers, seven tailors, 11 students, and 15 unemployed. The associations, to which 35 HSH belonged, were related to sexuality (66%), religion (20%), social matters (8%) and economy (6%). Sexual habits, according to anal intercourse, differentiated the "Ubbi" or receptive/passive (57%), the "Yoos" or incertif/active (25%), the "Ubbi/Yoos" who play the two roles (14%) and the "neitherUbbi/norYoos" who had other practices than anal (4%). Practices between men, concerned mutual strokes (100%), fellatio (61%) and anal intercourse (49%), counted 45% for remuneration, 35% of multi-unprotected partnership, and 12% of breaking condom. Practices with women were reported by 15 MSM (31%). Concerning STDs, at least one sign was reported by 43 MSM, one transmission way by 42, one mean of protection by 47; and the first recourse was a health system for 36 MSM. The test of HIV/AIDS screening was done by 38 HSH among which 30 withdrew the results. The "Ubby

    Full Text Available Abstract The HIV/AIDS epidemic has continued to pose significant challenges to countries in Sub-Saharan Africa. Millions of African children and youth have lost parents to HIV/AIDS leaving a generation of orphans to be cared for within extended family systems and communities. The experiences of youth who have lost parents to the HIV/AIDS epidemic provide an important ingress into this complex, evolving, multi-dimensional phenomenon. A fundamental qualitative descriptive study was conducted to develop a culturally relevant and comprehensive description of the experiences of orphanhood from the perspectives of Ugandan youth. A purposeful sample of 13 youth who had lost one or both parents to HIV/AIDS and who were affiliated with a non-governmental organization providing support to orphans were interviewed. Youth orphaned by HIV/AIDS described the experience of orphanhood beginning with parental illness, not death. Several losses were associated with the death of a parent including lost social capitol, educational opportunities and monetary assets. Unique findings revealed that youth experienced culturally specific stigma and conflict which was distinctly related to their HIV/AIDS orphan status. Exploitation within extended cultural family systems was also reported. Results from this study suggest that there is a pressing need to identify and provide culturally appropriate services for these Ugandan youth prior to and after the loss of a parent(s.

    To describe the antiretroviral therapy status of people living with HIV (PLHIV) who died of AIDS-related causes between 2009 and 2013. We conducted a cross-sectional, population-based study. Data were obtained by linking the mortality information system and the national ART dispensing database. Trends were modelled using linear regression analysis. A total of 61 425 AIDS-related deaths were registered in Brazil between 2009 and 2013. Median age at death was 41 years (IQR: 33-49), and 65.7% (40 337) of deaths were among men; 47.2% (29 004) of PLHIV who died during the study period had never started treatment, 7.0% (4274) had discontinued it, 15.9% (9775) were on ART for 6 months or less and 29.9% (18 372) were on ART for more than 6 months. Only 1.3% of PLHIV were on third-line ARV regimens when they died. AIDS-related mortality remains a challenge even in a context of sustained universal access to antiretroviral treatment due to failure of service provision, not to therapy failure. Robust health policies closing gaps in the HIV continuum of care are crucial to further reduce mortality. © 2016 John Wiley & Sons Ltd.

    2014-12-01

    Despite the widespread utilization of the mass media in HIV/AIDS prevention, little is known about the knowledge gap that results from disparities in mass media use. This study examined the relationship between HIV/AIDS-related mass media use and HIV/AIDS-related knowledge among urban and rural residents of northwestern Ethiopia. A hierarchical regression analysis indicated that HIV/AIDS-related mass media use has both sequestering and mainstreaming effects in certain segments of the study population, although it was not a significant predictor of HIV/AIDS-related knowledge in the total population. The knowledge gaps between individuals with high and low education and between individuals who experience high and low levels of interpersonal communication about HIV/AIDS narrowed as HIV/AIDS-related media use increased, but the gap between urban and rural residents widened. The widening gap could be explained by differences in perceptions of information salience and several theoretical assumptions. Current mass media information campaigns, which are often prepared and broadcast from urban centers, may not only fail to improve the HIV/AIDS knowledge of the rural populace but also put rural populations at a disadvantage relative to their urban counterparts. Communication interventions informed by socioecological models might be helpful to redress and/or narrow the widening knowledge gap between urban and rural residents. © The Author (2013).

    Currently, oral and maxillofacial surgery (OMFS) still poses a significant challenge for surgeons due to the anatomic complexity and limited field of view of the oral cavity. With the great development of computer technologies, he computer-aided surgery has been widely used for minimizing the risks and improving the precision of surgery. Areas covered: The major goal of this paper is to provide a comprehensive reference source of current and future development of computer-aided OMFS including surgical planning, simulation and navigation for relevant researchers. Expert commentary: Compared with the traditional OMFS, computer-aided OMFS overcomes the disadvantage that the treatment on the region of anatomically complex maxillofacial depends almost exclusively on the experience of the surgeon.

    2006-11-01

    Sub-Saharan Africa disproportionately represents the largest incidence of both HIV/AIDS and internal conflicts. The impact of conflict on HIV incidence is largely unknown. Current epidemiological evidence paradoxically suggests that in most populations affected by conflict, HIV prevalence is lower than surrounding communities. However, in situations of conflict, the most vulnerable populations, such as women and children, are at increased risk for HIV through sexual violence, forced occupational exposure and an absence of access to health care or testing. Together, these dimensions of conflict create a complex and challenging situation for prevention of HIV/AIDS and delivery of care to conflict-affected populations. We examine the complexity of monitoring HIV/AIDS in conflict settings. We argue that increased efforts are needed to protect vulnerable populations and design health-delivery systems that are sustainable in settings of conflict.

    Cancer is a significant cause of morbidity and mortality in people infected with the human immunodeficiency virus (HIV). In fact, 30–40% of people with this condition will develop a malignancy during their lifetime. The majority of cancers affecting HIV positive people are those established as AIDS defining: Kaposi’s sarcoma (KS), non-Hodgkin’s lymphoma (NHL) and invasive cervical cancer. However, other types of cancer also appear to be more common among those infected with HIV. While not classified as AIDS defining, these malignancies are affecting the HIV/AIDS community greatly and have been referred to as ‘AIDS-associated malignancies’ or ‘opportunistic’ cancers. Two analyses have revealed a two to three fold increase in the overall risk of developing these cancers. The introduction of highly active antiretroviral therapy (HAART) has resulted in decreased mortality and morbidity, and the majority of people in developed countries infected with HIV are living with only mild to moderate immunosuppression because of wide access to antiretroviral therapy. HIV positive persons have a markedly elevated risk for two malignancies: KS and NHL, which are themselves considered sufficient to signify progression to AIDS. KS and NHL are caused by a loss of immune control of latent infection with oncogenic viruses (human herpes virus 8 (HHV-8) for KS, Epstein–Barr virus for certain NHL subtypes). Other cancers caused by viruses (e.g. cervical and anal canal cancers caused by human papillomavirus (HPV), liver cancer caused by hepatitis B and C) also occur with increased frequency in this population, although for them, the importance of immune suppression is less clear.

    Development assistance targeting health overwhelmingly concentrates on HIV/AIDS. This column argues that that focus neglects critical demographic issues and degrades health infrastructure, particularly in Sub-Saharan Africa. The prime rule for AIDS aid should be “First, do no harm”.

    Model-based hearing aid development considers the assessment of speech recognition using a master hearing aid (MHA). It is known that aided speech recognition in noise is related to cognitive factors such as working memory capacity (WMC). This relationship might be mediated by hearing aid experience (HAE). The aim of this study was to examine the relationship of WMC and speech recognition with a MHA for listeners with different HAE. Using the MHA, unaided and aided 80% speech recognition thresholds in noise were determined. Individual WMC capacity was assed using the Verbal Learning and Memory Test (VLMT) and the Reading Span Test (RST). Forty-nine hearing aid users with mild to moderate sensorineural hearing loss divided into three groups differing in HAE. Whereas unaided speech recognition did not show a significant relationship with WMC, a significant correlation could be observed between WMC and aided speech recognition. However, this only applied to listeners with HAE of up to approximately three years, and a consistent weakening of the correlation could be observed with more experience. Speech recognition scores obtained in acute experiments with an MHA are less influenced by individual cognitive capacity when experienced HA users are taken into account.

    Full Text Available Abstract The AIDS Cancer and Specimen Resource (ACSR supports scientific discovery in the area of HIV/AIDS-associated malignancies. The ACSR was established as a cooperative agreement between the NCI (Office of the Director, Division of Cancer Treatment and Diagnosis and regional consortia, University of California, San Francisco (West Coast, George Washington University (East Coast and Ohio State University (Mid-Region to collect, preserve and disperse HIV-related tissues and biologic fluids and controls along with clinical data to qualified investigators. The available biological samples with clinical data and the application process are described on the ACSR web site. The ACSR tissue bank has more than 100,000 human HIV positive specimens that represent different processing (43, specimen (15, and anatomical site (50 types. The ACSR provides special biospecimen collections and prepares speciality items, e.g., tissue microarrays (TMA, DNA libraries. Requests have been greatest for Kaposi's sarcoma (32% and non-Hodgkin's lymphoma (26%. Dispersed requests include 83% tissue (frozen and paraffin embedded, 18% plasma/serum and 9% other. ACSR also provides tissue microarrays of, e.g., Kaposi's sarcoma and non-Hodgkin's lymphoma, for biomarker assays and has developed collaborations with other groups that provide access to additional AIDS-related malignancy specimens. ACSR members and associates have completed 63 podium and poster presentations. Investigators have submitted 125 letters of intent requests. Discoveries using ACSR have been reported in 61 scientific publications in notable journals with an average impact factor of 7. The ACSR promotes the scientific exploration of the relationship between HIV/AIDS and malignancy by participation at national and international scientific meetings, contact with investigators who have productive research in this area and identifying, collecting, preserving, enhancing, and dispersing HIV/AIDS-related

  17. HIV/AIDS knowledge, attitudes and behaviour of persons with and without disabilities from the Uganda Demographic and Health Survey 2011: Differential access to HIV/AIDS information and services.

    Full Text Available Uganda is among the first to use the Washington Group Short Set of Questions on Disability to identify persons with disabilities in its Demographic and Health Survey. In this paper, we review the HIV Knowledge, Attitudes and Behaviour component of the 2011 Ugandan Demographic and Health Survey, analysing a series of questions comparing those with and without disabilities in relation to HIV/AIDS knowledge, attitudes and practices. We found comparable levels of knowledge on HIV/AIDS for those with and those without disabilities in relation to HIV transmission during delivery (93.89%, 93.26% and through breastfeeding (89.91%, 90.63%, which may reflect increased attention to reaching the community of persons with disabilities. However, several gaps in the knowledge base of persons with disabilities stood out, including misconceptions of risk of HIV infection through mosquito bites and caring for a relative with HIV in own household (34.39%, 29.86%; p<0.001; 91.53%, 89.00%; p = 0.001, respectively. The issue is not just access to appropriate information but also equitable access to HIV/AIDS services and support. Here we found that persons with multiple disabilities were less likely than individuals without disabilities to return to receive results from their most recent HIV test (0.60[0.41-0.87], p<0.05. HIV testing means little if people do not return for follow-up to know their HIV status and, if necessary, to be connected to available services and supports. Additional findings of note were that persons with disabilities reported having a first sexual encounter at a slightly younger age than peers without disabilities; and persons with disabilities also reported having a sexually transmitted disease (STD within the last 12 months at significantly higher rates than peers without disabilities (1.38[1.18-1.63], p<0.01, despite reporting comparable knowledge of the need for safer sex practices. This analysis is among the first to use HIV/AIDS-related

    Full Text Available This article examines the relationship between the type of a development aid implementing organisation (public or private and the quality of project management in development aid. The author begins with main public administration considerations - how public aid administration is different from private and furthermore, how particular sectoral characteristics of organisations influence the quality of the management process. The article combines empirical findings on the differences between the public and private sector with a complex setting of development aid and main success factors in development aid activity, in order to determine whether for-profit or public companies are more likely to achieve better project management processes. The article identifies some indices that favorise private companies, and outlines further necessary steps that should be taken in order to broaden the argumentation and confirm or reject this assertion

    2017-12-04

    Efforts are currently underway by major orchestrators and funders of the global AIDS response to realise the vision of achieving an end to AIDS by 2030. Unlike previous efforts to provide policy guidance or to encourage 'best practice' approaches for combatting AIDS, the end of AIDS project involves the promotion of a clear set of targets, tools, and interventions for a final biomedical solution to the epidemic. In this paper, we examine the bureaucratic procedures of one major AIDS funder that helped to foster a common vision and mission amongst a global AIDS community with widely divergent views on how best to address the epidemic. We focus on the methods, movements, and materials that are central to the project of ending AIDS, including those related to biomedical forms of evidence and big data science. We argue that these approaches have limitations and social scientists need to pay close attention to the end of AIDS project, particularly in contexts where clinical interventions might transform clinical outcomes, but where the social, economic, and cultural determinants of HIV and AIDS remain largely intact and increasingly obscured.

    To explore factors influencing mortality rate of HIV/AIDS and to improve the effectiveness of antiretroviral therapy (ART). By means of retrospective cohort study and the AIDS control information system, HIV/AIDS case reports and antiviral treatment information of 4 cities in southern Shanxi province up to end of December 2012 were selected, to calculate the mortality rate and treatment coverage based on further data collected, along with analysis using the Cox proportional hazards survival regression. 4 040 cases confirmed of HIV/AIDS were included in this study. The average age was (36.0 ± 12.9) years, with 65.3% being male, 56.5% being married, 73.5% having junior high school education or lower, 58.4% being peasants, 54.3% with sexually transmitted infection (40.1% were heterosexual, 14.2% were homosexual), and 38.9% were infected via blood transmission (20.2% were former plasma donors, 16.2% blood transfusion or products recipients, 2.4% were injection drug users). Overall mortality decreased from 40.2 per 100 person/year in 2004 to 6.3 per 100 person/year in 2012, with treatment coverage concomitantly increasing from almost 14.8% to 63.4%. Cox proportional hazards survival regression was used on 4 040 qualified cases, demonstrating the top mortality risk factor was without antiretroviral therapy (RR = 14.9, 95% CI: 12.7-17.4). Cox proportional hazards survival regression was made on 1 938 cases of antiviral treatment, demonstrating that the mortality risk of underweight or obese before treatment was higher than those of normal and overweight cases (RR = 2.7, 95% CI: 1.6-4.5), and the mortality of those having a CD4(+) T-lymphocyte count ≤ 50 cells per µl before treatment was more than 50 cases (RR = 2.6, 95% CI: 1.5-4.5); Cox proportional hazards survival regression was made on 2 102 cases of untreated cases, demonstrating the mortality risk of those initially diagnosed as AIDS was higher than those initially diagnosed as HIV (RR = 3.4, 95% CI: 2

    Full Text Available An educational project on sexuality, STDs, and AIDS was conducted for four years with some 500 women. As a result, changes were observed in HIV-related knowledge and attitudes, but not in risk behaviors for infection. This fact motivated the development of a qualitative study to learn the reasons why women failed to incorporate HIV preventive behaviors into their daily lives. Six focus groups were conducted with women who had participated in the educational project. The analysis was thematic. Women were familiar with HIV transmission routes and preventive measures. They admitted not using condoms due to fear of being suspected of infidelity and because this might lead to separation of the couple. Women reported that relationships with their partners had been difficult because of lack of dialogue and that men always had the final word. Although women had information about AIDS, they did not use preventive measures in steady relationships because they did not wield decision-making power. Gender inequality and fidelity were two significant issues related to the increase in AIDS among women.Um projeto educativo sobre sexualidade, DST e AIDS foi realizado durante quatro anos com cerca de quinhentas mulheres. Como resultado, houve mudanças em conhecimentos e atitudes em relação ao HIV, mas não em comportamentos de risco para a infecção. Isto motivou a realização de um estudo qualitativo para conhecer as razões pelas quais as medidas de prevenção de AIDS não são incorporadas ao cotidiano das mulheres. Foram realizados seis grupos focais com mulheres que haviam participado do projeto educativo citado. A análise foi temática. As mulheres citaram todas as vias de transmissão e prevenção de AIDS. Reconheceram que não usavam condom porque tinham medo de despertar suspeita de infidelidade e provocar a separação do casal. Relataram que a relação a dois era difícil por falta de diálogo e que a palavra final era sempre do homem. Apesar

    This study investigated age-related changes in behavioral and neural complexity for a polyrhythmic movement, which appeared to be an exception to the loss of complexity hypothesis. Young (n = 15; age = 24.2 years) and older (15; 68.1 years) adults performed low-level force-tracking with isometric index abduction to couple a compound sinusoidal target. Multi-scale entropy (MSE) of tracking force and inter-spike interval (ISI) of motor unit (MU) in the first dorsal interosseus muscle were assessed. The MSE area of tracking force at shorter time scales of older adults was greater (more complex) than that of young adults, whereas an opposite trend (less complex for the elders) was noted at longer time scales. The MSE area of force fluctuations (the stochastic component of the tracking force) were generally smaller (less complex) for older adults. Along with greater mean and coefficient of ISI, the MSE area of the cumulative discharge rate of elders tended to be lower (less complex) than that of young adults. In conclusion, age-related complexity changes in polyrhythmic force-tracking depended on the time scale. The adaptive behavioral consequences could be multi-factorial origins of the age-related impairment in rate coding, increased discharge noises, and lower discharge complexity of pooled MUs.

  10. SRSF1-3 contributes to diversification of the immunoglobulin variable region gene by promoting accumulation of AID in the nucleus.

    Activation-induced cytidine deaminase (AID) is essential for diversification of the Ig variable region (IgV). AID is excluded from the nucleus, where it normally functions. However, the molecular mechanisms responsible for regulating AID localization remain to be elucidated. The SR-protein splicing factor SRSF1 is a nucleocytoplasmic shuttling protein, a splicing isoform of which called SRSF1-3, has previously been shown to contribute to IgV diversification in chicken DT40 cells. In this study, we examined whether SRSF1-3 functions in IgV diversification by promoting nuclear localization of AID. AID expressed alone was localized predominantly in the cytoplasm. In contrast, co-expression of AID with SRSF1-3 led to the nuclear accumulation of both AID and SRSF1-3 and the formation of a protein complex that contained them both, although SRSF1-3 was dispensable for nuclear import of AID. Expression of either SRSF1-3 or a C-terminally-truncated AID mutant increased IgV diversification in DT40 cells. However, overexpression of exogenous SRSF1-3 was unable to further enhance IgV diversification in DT40 cells expressing the truncated AID mutant, although SRSF1-3 was able to form a protein complex with the AID mutant. These results suggest that SRSF1-3 promotes nuclear localization of AID probably by forming a nuclear protein complex, which might stabilize nuclear AID and induce IgV diversification in an AID C-terminus-dependent manner.

  11. Low Delay Noise Reduction and Dereverberation for Hearing Aids

    Directory of Open Access Journals (Sweden)

    Heinrich W. Löllmann

    2009-01-01

    Full Text Available A new system for single-channel speech enhancement is proposed which achieves a joint suppression of late reverberant speech and background noise with a low signal delay and low computational complexity. It is based on a generalized spectral subtraction rule which depends on the variances of the late reverberant speech and background noise. The calculation of the spectral variances of the late reverberant speech requires an estimate of the reverberation time (RT which is accomplished by a maximum likelihood (ML approach. The enhancement with this blind RT estimation achieves almost the same speech quality as by using the actual RT. In comparison to commonly used post-filters in hearing aids which only perform a noise reduction, a significantly better objective and subjective speech quality is achieved. The proposed system performs time-domain filtering with coefficients adapted in the non-uniform (Bark-scaled frequency-domain. This allows to achieve a high speech quality with low signal delay which is important for speech enhancement in hearing aids or related applications such as hands-free communication systems.

    Despite various HIV and AIDS training programmes offered for educators by the South African Department of Education, little has been achieved at the level of management in terms of creating a wider understanding of the social and cultural complexities of the condition and its impact on the quality of teaching and learning. Specifically, there is a lack of developmental programmes to help school principals provide leadership that can ensure that teachers and children who live in a context affected by the disease will still find themselves in a school environment of quality, care and compassion. With this in mind, we conducted a qualitative research enquiry among a sample of 12 school principals in the Eastern Cape Province in order to discover their perceptions about the impacts of HIV and AIDS on their schools and to learn how they have responded to the corresponding challenges. Our intention was to use the findings primarily to inform the development of an academic programme and short courses to empower school principals and leadership in this regard, but the findings may also be relevant as a guide for research on a larger scale.

  13. Epidemiology of AIDS in Africa--part 2.

    Cigielski, J P

    1988-03-01

    A recently completed study involving over 10,000 people from 6 Central African countries found seroprevalence rates generally under 1% for the acquired immunodeficiency syndrome (AIDS); however, rates were significantly higher for urban residents, prostitutes and their sexual contacts, and patients attending sexually transmitted disease clinics. The 4 major modes of transmission of AIDS in Africa are sexual contact, perinatal transmission, transfusion of infected blood or blood products, and the reuse of equipment such as needles and syringes. In 1985, a 2nd AIDS virus, human immunodeficiency virus (HIV)-2, was discovered in West Africa--a finding with important implications for epidemiologic surveillance, screening programs, and clinical diagnostic testing. Although 45 of the 50 African countries have developed concrete public health policies and strategies for the prevention and control of AIDS, most nations of sub-Saharan Africa lack the economic and social resources to implement these programs effectively. Thus, international cooperation and a commitment on the part of the US and Western Europe to provide assistance will be essential. Needs must be addressed on 2 fronts: treatment of those already infected or suffering from the disease and containment of the AIDS epidemic. Public health efforts should focus initially on high risk behaviors through health education. At the same time, it should be recognized that AIDS is not the largest health issue facing Africans, and there is a complex interaction between AIDS and other health problems such as malnutrition, genital ulcers, diarrhea, and tuberculosis. An approach to AIDS requires an expansion of public health initiatives in areas such as clean water supplies, maternal-child health programs, nutrition and immunization programs, and sexually transmitted disease clinics.

    Fifty-eight patients with AIDS disease were studied with MR imaging in the aim of detecting the grade of brain involvement. The examinations were performed with a 1.5 Tesla magnet. Thirty-seven showed white matter lesion (63.5%), twenty-five patients showed cerebral atrophy (43%), in eight patients the MR appearance was consistent with toxoplasmosis infection (13.5%), two patients showed a linfoma (3.4%) and two patients micrococcosis (3.4%). Seventeen out of the thirty-seven patients with white matter disease showed focal well circumscribed lesion (46%), while twenty showed diffuse involvement. Between the twenty-five patients with cerebral atrophy, twelve showed a prevalence of the cortical involvement and eight a subcortical atrophy. In five patients a concomitant, cortical and subcortical atrophy was found. Between the eight patients with neurotoxolesion and two of them a widespread encephalitis picture. The MR appearance of the two limphomas was that of periventricular, space occupying, masses. In two patients with micrococcis a nodular aspect of leptomeningeal lesions was found.

  15. HIV/AIDS communication in four Nigerian mainstream newspapers.

    One consensus in discussions on HIV/AIDS communication in low and middle income countries (LMICs) is the need for communication models to focus on activity rather than cognitive indicators in order to achieve desired improvements in health behaviors and outcomes. Past failures of HIV/AIDS communication efforts in LMICs have been attributed to emphasis on cognitive indicators. This study analyses HIV/AIDS communication models in Nigerian newspapers. Data were obtained through analysis of manifest content of four Nigerian papers issued between 2002 and 2004. Frequency, prominence and space dedicated to HIV/AIDS-related topics were measured. Descriptive statistics were used to highlight the frequency and percentage of cognitive- and activity-oriented information on HIV/AIDS. A total of 464 HIV/AIDS-related articles were identified. Fifty-nine percent (274) of articles were activity-oriented. Over half of articles were news stories. No news story made front and back pages lead. There were only nine editorials on HIV/AIDS. This study shows that the activity model of HIV/AIDS communication dominates the four Nigerian mainstream newspapers studied. However, it is worth noting the limited number of editorials and feature articles, which have the capacity to stimulate debate and foster a social environment in which AIDS is addressed in a spirit of openness. For a country that has the third largest number of people living with HIV/AIDS globally, one would expect the mass media to deliberately play an instrumental and a more active role in the battle against the disease by engaging in in-depth contextual discourse on HIV/AIDS.

    In undertaking a major revision to the Australian Refined Diagnosis Related Group (ARDRG) classification, we set out to contrast Australia's approach to using data on additional (not principal) diagnoses with major international approaches in splitting base or Adjacent Diagnosis Related Groups (ADRGs). Comparative policy analysis/narrative review of peer-reviewed and grey literature on international approaches to use of additional (secondary) diagnoses in the development of Australian and international DRG systems. European and US approaches to characterise complexity of inpatient care are well-documented, providing useful points of comparison with Australia's. Australia, with good data sources, has continued to refine its national DRG classification using increasingly sophisticated approaches. Hospital funders in Australia and in other systems are often under pressure from provider groups to expand classifications to reflect clinical complexity. DRG development in most healthcare systems reviewed here reflects four critical factors: these socio-political factors, the quality and depth of the coded data available to characterise the mix of cases in a healthcare system, the size of the underlying population, and the intended scope and use of the classification. Australia's relatively small national population has constrained the size of its DRG classifications, and development has been concentrated on inpatient care in public hospitals. Development of casemix classifications in health care is driven by both technical and socio-political factors. Use of additional diagnoses to adjust for patient complexity and cost needs to respond to these in each casemix application. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  17. Work-related musculoskeletal disorders and ergonomic risk factors in special education teachers and teacher’s aides

    2016-02-01

    Full Text Available Abstract Background Work-related musculoskeletal disorders (WMSDs have become increasingly common among health-related professionals. Special education personnel who serve students with disabilities often experience physical strains; however, WMSDs have been overlooked in this population. The objectives of this study were to investigate the work-related ergonomics-associated factors in this population and to evaluate their correlation with the WMSDs prevalence. Methods A questionnaire with three domains, namely demographics, prevalence of work-related musculoskeletal disorders, and ergonomic factors, designed by our research team was delivered to educators who work in special education schools. Results Approximately 86 % of the 388 special education school teachers and teacher’s aides in this study experienced musculoskeletal disorders. The lower back, shoulder, and wrist were the three most affected regions. A logistic regression analysis revealed that the participants’ background factors, namely >5.5 years of experience (odds ratio [OR] = 4.090, 95 % CI: 1.350-12.390, students with multiple disorders (OR = 2.412, 95 % CI: 1.100-5.287, and other work-related ergonomic factors (assistance in diaper changing and others duties, were strongly associated with the prevalence of WMSD. Nap habit (OR = 0.442, 95 % CI: 0.230-0.851 and having teaching partners in the same class (OR = 0.486, 95 % CI: 0.250-0.945 resulted in low possibility of acquiring WMSDs. The use of supportive devices was associated with a low WMSD prevalence. Conclusions The present study revealed an association between WMSDs and specific job features among teachers and teacher’s aides in special education schools. Future efforts should emphasize examining safe student-handling ergonomics, formulating policies regarding student-teacher ratio, incorporating mandatory break times at the workplaces, and promoting personal health for preventing work-related

    Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters.

    2017-08-04

    Home health aides (HHAs) work in a high-risk industry and experience high rates of work-related injury that have been significantly associated with reduction in workers and organisational productivity, quality and performance. The main objective of the study was to examine how worker environment and ergonomic factors affect HHA risk for reporting occupational injuries. We used cross-sectional analysis of data from the 2007 National Home Health and Hospice Aide Survey (NHHAS). The study sample consisted of a nationally represented sample of home health aides (n=3.377) with a 76.6% response rate. We used two scales 1 : a Work Environment Scale and 2 an Ergonomic Scale. Univariate and bivariate analyses were conducted to describe HHA work-related injury across individual, job and organisational factors. To measure scale reliability, Cronbach's alphas were calculated. Multivariable logistic regression was used to determine predictors of reported occupational injury. In terms of Work Environment Scale, the injury risk was decreased in HHAs who did not consistently care for the same patients (OR=0.96, 95% CI: 0.53 to 1.73). In terms of Ergonomic Scale, the injury risk was decreased only in HHAs who reported not needing any other devices for job safety (OR=0.30, 95% (CI): 0.15 to 0.61). No other Work Environment or Ergonomic Scale factors were associated with HHAs' risk of injury. This study has great implications on a subcategory of the workforce that has a limited amount of published work and studies, as of today, as well as an anticipated large demand for them. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The primary purpose of this study was to assess the role, status and scope of workplace HIV/AIDS committees as a means of effective workplace governance of the HIV/AIDS impact, and their role in extending social protective HIV/AIDS-related rights to employees. In-depth qualitative case studies were conducted in five South African small and medium-sized enterprises (SMEs) that were actively implementing HIV/AIDS policies and programmes. Companies commonly implemented HIV/AIDS policies and programmes through a workplace committee dedicated to HIV/AIDS or a generic committee dealing with issues other than HIV/ AIDS. Management, through the human resources department and the occupational health practitioner often drove initial policy formulation, and had virtually sole control of the HIV/AIDS budget. Employee members of committees were mostly volunteers, and were often production or blue collar employees, while there was a notable lack of participation by white-collar employees, line management and trade unions. While the powers of workplace committees were largely consultative, employee committee members often managed in an indirect manner to secure and extend social protective rights on HIV/AIDS to employees, and monitor their effective implementation in practice. In the interim, workplace committees represented one of the best means to facilitate more effective workplace HIV/AIDS governance. However, the increased demands on collective bargaining as a result of an anticipated rises in AIDS-related morbidity and mortality might prove to be beyond the scope of such voluntary committees in the longer term.

  1. Challenging empowerment: AIDS-affected South African children and the need for a multi-level relational approach.

    2014-01-01

    Critics of empowerment have highlighted the concept's mutability, focus on individual transformation, one-dimensionality and challenges of operationalisation. Relating these critiques to children's empowerment raises new challenges. Drawing on scholarship on children's subjecthood and exercise of power, alongside empirical research with children affected by AIDS, I argue that empowerment envisaged as individual self-transformation and increased capacity to act independently offers little basis for progressive change. Rather it is essential to adopt a relational approach that recognises the need to transform power relationships at multiple levels. This analysis has implications for our wider understanding of empowerment in the 21st century.

    This study reviewed evidence on the effects of nonresuscitative first aid training on competence and helping behavior in laypersons. We identified randomized and nonrandomized controlled trials and interrupted time series on nonresuscitative first aid training for laypersons by using 12 databases (including MEDLINE, EMBASE, and PsycINFO), hand searching, reference checking, and author communication. Two reviewers independently evaluated selected studies with the Cochrane Effective Practice and Organisation of Care Review Group quality criteria. One reviewer extracted data with a standard form and another checked them. In anticipation of substantial heterogeneity across studies, we elected a descriptive summary of the included studies. We included 4 studies, 3 of which were randomized trials. We excluded 11 studies on quality issues. Two studies revealed that participants trained in first aid demonstrated higher written test scores than controls (poisoning first aid: relative risk 2.11, 95% confidence interval [CI] 1.64 to 2.72; various first aid cases: mean difference 4.75, 95% CI 3.02 to 6.48). Two studies evaluated helping responses during unannounced simulations. First aid training improved the quality of help for a bleeding emergency (relative risk 25.94; 95% CI 3.60 to 186.93), not the rate of helping (relative risk 1.13; 95% CI 0.88 to 1.45). Training in first aid and helping behavior increased the helping rates in a chest pain emergency compared with training in first aid only (relative risk 2.80; 95% CI 1.05 to 7.50) or controls (relative risk 3.81; 95% CI 0.98 to 14.89). Participants trained in first aid only did not help more than controls (relative risk 1.36; 95% CI 0.28 to 6.61). First aid programs that also train participants to overcome inhibitors of emergency helping behavior could lead to better help and higher helping rates.

    1997-01-01

    Purpose: To catalogue the presenting symptoms of patients with AIDS who are presumed to have primary central nervous system lymphoma (PCNSL). To document the palliative efficacy of cranial irradiation (RT) relative to the endpoints of complete and overall response for the respective symptoms. Methods: An analysis of 163 patients with AIDS-related PCNSL who were evaluated at nine urban hospitals was performed. These patients were treated for PCNSL after the establishment of a tissue diagnosis or on a presumptive basis after failing empiric treatment for toxoplasmosis. All patients were treated between 1983 and 1995 with radiotherapy (median dose-fractionation scheme = 3 Gy x 10) and steroids (>90% dexamethasone). Because multiple fractionation schemes were used, prescriptions were converted to biologically effective doses according to the formula, Gy 10 = Total Dose x (1 + fractional dose/α-β); using an α-β value of 10. Results: The overall palliative response rate for the entire group was 53%. In univariate analysis, trends were present associating complete response rates with higher performance status (KPS ≥ 70 vs. KPS ≤ 60 = 17% vs. 5%), female gender (women vs. men = 29% vs. 8%), and the delivery of higher biologically effective doses (BED) of RT (Gy 10 > 39 vs. ≤ 39 = 20% vs. 5%). In multivariate analysis of factors predicting complete response, both higher KPS and higher BED retained independent significance. A separate univariate analysis identified high performance status (KPS ≥ 70 vs. KPS ≤ 60 = 71% vs. 47%), and young age (≤ 35 vs. > 35 = 61% vs. 40%) as factors significantly correlating with the endpoint of the overall response. In multivariate analysis, high performance status and the delivery of higher biologically effective doses of irradiation correlated significantly with higher overall response rates. Conclusion: Most AIDS patients who develop symptoms from primary lymphoma of the brain can achieve some palliation from a management

  5. Sources of AIDS awareness among women in India.

    Pallikadavath, S; Sreedharan, C; Stones, R W

    2006-01-01

    Sources of AIDS awareness among rural and urban Indian women were analysed using data from the National Family and Health Survey (1998-2000). Two measures were developed to study the impact each source had on knowledge. 'Effectiveness' was defined as the proportion of women who had heard of AIDS from only one source, from among women who had heard of AIDS from that particular source and other sources. 'Independent effect' was the proportion who had heard of AIDS from only one source in relation to all women who had heard of AIDS. Television was the most effective medium, and also had the highest independent effect. Radio and print had very low effectiveness and independent effect. Although television and print audiences are growing in India, it is likely a sub-group of women will continue to lack media access. There is an urgent need to disseminate AIDS awareness to this 'media underclass'. Since the media will not reach this group, other sources including health workers, community level activities such as adult education programmes, and networks of friends and relatives need to be explored.

  6. Financing the response to AIDS: some fiscal and macroeconomic considerations.

    2008-07-01

    This article examines the international response to AIDS from a fiscal perspective: first the financing of the international response to AIDS, especially the role of external financing, and second, a more comprehensive perspective on the costs of the national response to AIDS relevant for fiscal policy. The second half of the article focuses on the effectiveness of the response to AIDS. We find that there is little basis for concerns about macroeconomic constraints to scaling up, in light of the moderate scale of AIDS-related aid flows relative to overall aid. Regarding sectoral constraints, the picture is more differentiated. Many countries with high prevalence rates have also achieved high rates of access to treatment, but most of these are middle-income countries. Our econometric analysis credits external aid as a key factor that has enabled higher-prevalence countries to cope with the additional demands for health services. At the same time, gross domestic product per capita and health sector capacities are important determinants of access to treatment.

  7. Making mobility-related disability better: a complex response to a complex problem.

    2012-10-15

    Mobility disability in older adults can arise from single system problems, such as discrete musculoskeletal injury. In frail older adults, however, mobility disability is part of a complex web of problems. The approach to their rehabilitation must take that complexity into account, as is reported by Fairhall et al. First, their overall health state must be assessed, which is achieved by a comprehensive geriatric assessment. The assessment can show how a particular patient came to be disabled, so that an individualized care plan can be worked out. Whether this approach works in general can be evaluated by looking at group differences in mean mobility test scores. Knowing whether it has worked in the individual patient requires an individualized measure. This is because not every patient starts from the same point, and not every patient achieves success by aiming for the same goal. For one patient, walking unassisted for three metres would be a triumph; for another it would be a tragedy. Unless we understand the complexity of the needs of frail older adults, we will neither be able to treat them effectively nor evaluate our efforts sensibly.Please see related article http://www.biomedcentral.com/1741-7015/10/120.

    2017-09-01

    A rate-based understanding of home care aides' adverse occupational outcomes related to their work location and care tasks is lacking. Within a 30-month, dynamic cohort of 43 394 home care aides in Washington State, injury rates were calculated by aides' demographic and work characteristics. Injury narratives and focus groups provided contextual detail. Injury rates were higher for home care aides categorized as female, white, 50 to working through an agency (versus individual providers). In addition to direct occupational hazards, variability in workload, income, and supervisory/social support is of concern. Policies should address the roles and training of home care aides, consumers, and managers/supervisors. Home care aides' improved access to often-existing resources to identify, manage, and eliminate occupational hazards is called for to prevent injuries and address concerns related to the vulnerability of this needed workforce. © 2017 Wiley Periodicals, Inc.

    Full Text Available Human immunodeficiency virus and the acquired immunodeficiency syndrome (HIV/AIDS have greatly complicated dermatologic disease and the required care in most regions of Africa. Opportunistic infections, ectoparasites, Kaposi sarcoma, and skin manifestations of systemic infections are exceedingly common in patients with HIV/AIDS. Dermatologists have contributed significantly to our knowledge base about HIV/AIDS and have played an important educational role regarding the clinical manifestations historically. Because of the increased burden of skin disease in Africa due to the HIV/AIDS epidemic we must redouble our efforts to provide dermatology education to care providers in Africa. We review the burden of skin disease in Africa, how it relates to HIV/AIDS and global infectious disease, current educational strategies in Africa to address this need, and suggest potential solutions to move these efforts forward.

    Three-and-a-half decades on, no cure or vaccine is yet on the horizon for HIV, making effective behavior change communication (BCC) the key preventive strategy. Despite considerable success, HIV/AIDS BCC efforts have long been criticized for their primary focus on the individual-level field of influence, drawing on the more reductionist view of causation at the individual level. In view of this, we conducted a series of studies that employed a household survey, field experiment, and textual content analysis, and explored the macro-social-level effects of HIV/AIDS-related media and messages on HIV/AIDS cognitive and affective outcomes in Ethiopia. Against a backdrop of epidemiological and socioecological differences, urban versus rural residence has emerged as an important community-level factor that impacts HIV/AIDS-related media and message consumption processes and associated outcomes. The central thread crossing through the six studies included in this paper demonstrates that urban and rural people in high HIV prevalence contexts differ in their concern about and information needs on HIV/AIDS, HIV/AIDS-related media use, and HIV/AIDS-related cognitive and affective outcomes, as well as in their reaction to differently designed/framed HIV prevention messages. This paper proposes that HIV prevention media and message effects in high epidemic situations should be considered from a larger community-level perspective and calls for a socioecological approach to AIDS communication in the hard-hit sub-Saharan Africa. With a number of concrete recommendations to current and future HIV/AIDS BCC efforts in the region, the study joins an emerging body of health communication literature and theorizing that suggests the need to consider media and message effects from a macro-social perspective.

    To examine the association of cognitive function, age, and hearing loss with clinically assessed hearing aid benefit in older hearing-impaired persons. Hearing aid benefit was assessed using objective measures regarding speech recognition in quiet and noisy environments as well as a subjective measure reflecting everyday situations captured using a standardized questionnaire. A broad range of general cognitive functions such as attention, memory, and intelligence were determined using different neuropsychological tests. Linear regression analyses were conducted with the outcome of the neuropsychological tests as well as age and hearing loss as independent variables and the benefit measures as dependent variables. Thirty experienced older hearing aid users with typical age-related hearing impairment participated. Most of the benefit measures revealed that the participants obtained significant improvement with their hearing aids. Regression models showed a significant relationship between a fluid intelligence measure and objective hearing aid benefit. When individual hearing thresholds were considered as an additional independent variable, hearing loss was the only significant contributor to the benefit models. Lower cognitive capacity - as determined by the fluid intelligence measure - was significantly associated with greater hearing loss. Subjective benefit could not be predicted by any of the variables considered. The present study does not give evidence that hearing aid benefit is critically associated with cognitive function in experienced hearing aid users. However, it was found that lower fluid intelligence scores were related to higher hearing thresholds. Since greater hearing loss was associated with a greater objective benefit, these results strongly support the advice of using hearing aids regardless of age and cognitive function to counter hearing loss and the adverse effects of age-related hearing impairment. Still, individual cognitive capacity might

    Zinc oxide (ZnO) is a wide band gap semiconductor and a potential candidate for next generation white solid state lighting applications. In this work, hydrogen-related complexes in lithium diffused ZnO single crystals were studied. In addition to the well-known Li-OH complex, several other hydrogen defects were observed. When a mixture of Li2O and ZnO is used as the dopant source, zinc vacancies are suppressed and the bulk Li concentration is very high (>1019 cm-3). In that case, the predominant hydrogen complex has a vibrational frequency of 3677 cm-1, attributed to surface O-H species. When Li2CO3 is used, a structured blue luminescence band and O-H mode at 3327 cm-1 are observed at 10 K. These observations, along with positron annihilation measurements, suggest a zinc vacancy-hydrogen complex, with an acceptor level ˜0.3 eV above the valence-band maximum. This relatively shallow acceptor could be beneficial for p-type ZnO.

    Full Text Available Patients infected with HIV have a significantly increased risk of developing non-Hodgkin lymphomas despite the widespread use of HAART. To investigate mTOR pathway activity in acquired immunodeficiency syndrome (AIDS related diffuse large B-cell lymphoma AR-DLBCL, we used immunohistochemistry to examine the presence of the phosphorylated 70 ribosomal S6 protein-kinase (p70S6K, an extensively studied effector of mTOR Complex 1 (mTORC1 and the phosphorylated phosphatase and tensin homolog (pPTEN, a negative regulator of mTORC1 pathway.We evaluated tissue samples from 126 patients with AR-DLBCL. Among them, 98 samples were from tissue microarrays (TMAs supplied by the Aids and Cancer Specimen Resource (ACSR, the remaining 28 samples were from cases diagnosed and treated at the University of California, San Diego (UCSD. The presence of p70S6K was evaluated with two antibodies directed against the combined epitopes Ser235/236 and Ser240/244, respectively; and additional monoclonal anti-bodies were used to identify pPTEN and phosphorylated proline-rich Akt substrate of 40kDa (pPRAS40. The degree of intensity and percentage of cells positive for p70S6K and pPTEN were assessed in all the samples. In addition, a subgroup of 28 patients from UCSD was studied to assess the presence of pPRAS40, an insulin-regulated activator of the mTORC1. The expression of each of these markers was correlated with clinical and histopathologic features.The majority of the patients evaluated were males (88%; only two cases (1.6% were older than 65 years of age. We found high levels of both p70S6K-paired epitopes studied, 48% positivity against Ser235/236 (44% in ACSR and 64% in UCSD group, and 86% positivity against Ser240/244 (82% in ACSR and 100% in UCSD group. We observed more positive cells and stronger intensity with epitope Ser240/244 in comparison to Ser235/236 (p<0.0001.

    Most studies on sexual behavior have approached the relationship between AIDS knowledge and sexual behavior unidirectionally. This paper sets out to examine a reciprocal relationship between AIDS knowledge and sexual behavior, in which it is possible that adolescents who enter into sexuality may start to actively seek out information on sex. Additionally, the effects of various sources for AIDS-related information and condom use are analyzed. Data from the Flemish Educational Assessment project, which surveyed a sample of adolescents from the 3rd and 5th years of secondary school, were used. Results indicate that the relationship between AIDS knowledge and sexual behavior is quite complex. On one hand, we find that better knowledge leads to a later onset of sexuality and more consistent condom use; on the other hand, we find that adolescents who start sex earlier and use condoms inconsistently tend to be more knowledgeable about AIDS.

    1991-01-01

    This article considers the epidemic proportion of AIDS in developing countries, and discusses the U.S. Agency for International Development's (USAID) reworked and intensified strategy for HIV infection and AIDS prevention and control over the next 5 years. Developing and launching over 650 HIV and AIDS activities in 74 developing countries since 1986, USAID is the world's largest supporter of anti-AIDS programs. Over $91 million in bilateral assistance for HIV and AIDS prevention and control have been committed. USAID has also been the largest supporter of the World Health Organization's Global Program on AIDS since 1986. Interventions have included training peer educators, working to change the norms of sex behavior, and condom promotion. Recognizing that the developing world will increasingly account for an ever larger share of the world's HIV-infected population, USAID announced an intensified program of estimated investment increasing to approximately $400 million over a 5-year period. Strategy include funding for long-term, intensive interventions in 10-15 priority countries, emphasizing the treatment of other sexually transmitted diseases which facilitate the spread of HIV, making AIDS-related policy dialogue an explicit component of the Agency's AIDS program, and augmenting funding to community-based programs aimed at reducing high-risk sexual behaviors. The effect of AIDS upon child survival, adult mortality, urban populations, and socioeconomic development in developing countries is discussed. Program examples are also presented.

  4. Semiotic aspects of control and modeling relations in complex systems

    Energy Technology Data Exchange (ETDEWEB)

    Joslyn, C.

    1996-08-01

    A conceptual analysis of the semiotic nature of control is provided with the goal of elucidating its nature in complex systems. Control is identified as a canonical form of semiotic relation of a system to its environment. As a form of constraint between a system and its environment, its necessary and sufficient conditions are established, and the stabilities resulting from control are distinguished from other forms of stability. These result from the presence of semantic coding relations, and thus the class of control systems is hypothesized to be equivalent to that of semiotic systems. Control systems are contrasted with models, which, while they have the same measurement functions as control systems, do not necessarily require semantic relations because of the lack of the requirement of an interpreter. A hybrid construction of models in control systems is detailed. Towards the goal of considering the nature of control in complex systems, the possible relations among collections of control systems are considered. Powers arguments on conflict among control systems and the possible nature of control in social systems are reviewed, and reconsidered based on our observations about hierarchical control. Finally, we discuss the necessary semantic functions which must be present in complex systems for control in this sense to be present at all.

    1994-03-01

    As part of a community based educational campaign to convey the risk of HIV infection and AIDS to commercial sex workers in Jakarta, over 600 male transvestites (WARIA) were questioned about their sexual behavior patterns and their knowledge and attitude towards HIV infection and AIDS. Most expressed a genuine fear about AIDS, but they stated they did not have sufficient information to determine if their risk of infection, at this time, was great enough to command a change in their sexual conduct. Among the group who felt they were not at risk for HIV infection, 40% had 8 or more different sex partners per week. Low risk receptive oral sex, thigh massage (simulated vaginal sex) and masturbation of the client were routine activities but high risk receptive anal sex without condoms was most common. Despite such high risk behavior, the WARIA community remains free of HIV infections. However, if they refuse to accept the endorsement of their peer leaders and they fail to alter their sexual behavior because of an unawareness of their risk, that status will change soon.

Inúmeras ações, instituições e discursos começaram a emergir em nossa cultura, produzindo "verdades" sobre essa população. Utilizando o referencial teórico de Michael Foucault e dos estudos culturais, realizei um estudo com o objetivo de problematizar discursos sobre infância, adolescência e AIDS. Os resultados indicam que, nas práticas discursivas e não discursivas relativas às casas de apoio, sexualidade e revelação do diagnóstico, emergem modos de conceber a infância, a adolescência e a AIDS que vão "inventando" as crianças e adolescentes vivendo com HIV/AIDS.

    Full Text Available AIDS-related stigma and mental disorders are the most common conditions in people living with HIV (PLHIV. We therefore conducted this study to examine the association of AIDS-related stigma and discrimination with mental disorders among PLHIV in Cambodia.A two-stage cluster sampling method was used to select 1,003 adult PLHIV from six provinces. The People Living with HIV Stigma Index was used to measure stigma and discrimination, and a short version of general health questionnaire (GHQ-12 was used to measure mental disorders. Multivariate logistic regression analysis was conducted.The reported experiences of discrimination in communities in the past 12 months ranged from 0.8% for reports of being denied health services to 42.3% for being aware of being gossiped about. Internal stigma was also common ranging from 2.8% for avoiding going to a local clinic and/or hospital to 59.6% for deciding not to have (more children. The proportions of PLHIV who reported fear of stigma and discrimination ranged from 13.9% for fear of being physically assaulted to 34.5% for fear of being gossiped about. The mean score of GHQ-12 was 3.2 (SD = 2.4. After controlling for several potential confounders, higher levels of mental disorders (GHQ-12≥ 4 remained significantly associated with higher levels of experiences of stigma and discrimination in family and communities (AOR = 1.9, 95% CI = 1.4-2.6, higher levels of internal stigma (AOR = 1.7, 95% CI = 1.2-2.3, and higher levels of fear of stigma and discrimination in family and communities (AOR = 1.5, 95% CI = 1.1-2.2.AIDS-related stigma and discrimination among PLHIV in Cambodia are common and may have potential impacts on their mental health conditions. These findings indicate a need for community-based interventions to reduce stigma and discrimination in the general public and to help PLHIV to cope with this situation.

    2001-01-01

    This study is part of a line of research on gender and prevention in a research program on the social construction of HIV/AIDS. We present the results of an ethnographic study among low-income women 15-35 years old in the southern area of Buenos Aires. The area has the highest number of HIV/AIDS cases and high poverty levels, extensive social degradation, and urban violence. According to our results, in the interface between "knowing about" and "behaving" there are complex processes involving stigmatized and gender-biased representations of HIV/AIDS as "other people's problem" and social and sexual relations permeated by gender stereotypes and roles. We believe that planning of prevention should be based on the consideration of overall social practices and specifically the characteristics of gender relations, prioritizing relational strategies between women and men and promoting critical reflection on the main nodes organizing daily life and active participation in the production of social relations and practices of reciprocity and equity. The increasingly precarious conditions in social life intensifies poor women's vulnerability and social interaction contexts that relate to the socioeconomic and symbolic role played by women.

    2017-06-17

    This cross-sectional study examined the actor and partner effects of beliefs about AIDS-related death on quality of life in Chinese married couples in which both were living with HIV. A total of 49 married couples in central China who were both infected with HIV completed measures to assess their beliefs about AIDS-related death and quality of life. In the actor-partner interdependence model, the husband-wife dyad showed congruence in their beliefs about AIDS-related death (r = .40) and quality of life-mental health summary (r = .31), respectively, within the couple. Both actor and partner effects of beliefs about AIDS-related death on the quality of life-mental health summary, rather than the quality of life-physical health summary, were significant within the husband-wife dyad. Our findings indicate the dyadic interdependence of beliefs about AIDS-related death and the quality of life-mental health summary in married couples. Psychosocial interventions that target a reduction of negative death beliefs and enhancement of well-being in the context of HIV should treat the couple as a unit.

    Patient-related complexity in nursing care - Collective case studies in the acute care hospital Abstract. Patient-related complexity of nursing is defined by the three characteristics "instability", "uncertainty", and "variability". Complexity increased in the past years, due to reduced hospital length of stay and a growing number of patients with chronic and multiple diseases. We investigated the phenomenon of patient-related complexity from the point of view of nurses and clinical nurse specialists in an acute care hospital. In the context of a collective case study design, nurses and clinical nurse specialists assessed the complexity of nursing situations with a questionnaire. Subsequently, we interviewed nurses and clinical nurse specialists about their evaluation of patient-related complexity. In a within-case-analysis we summarized data inductively to create case narratives. By means of a cross-case-analysis we compared the cases with regard to deductively derived characteristics. The four cases exemplarily showed that the degree of complexity depends on the controllability and predictability of clinical problems. Additionally, complexity increases or decreases, according to patients' individual resources. Complex patient situations demand professional expertise, experience, communicative competencies and the ability for reflection. Beginner nurses would benefit from support and advice by experienced nurses to develop these skills.

    The aim of the present study was to evaluate the power of magnification required, reading performance with low-vision aids and vision-related quality of life with reference to reading ability and ability to carry out day-to-day activities in patients after macular translocation. This study included 15 patients who had undergone macular translocation with 360-degree peripheral retinectomy. The mean length of follow-up was 19.2 +/- 10.8 months (median 11 months). At the final examination, the impact of visual impairment on reading ability and quality of life was assessed according to a modified 9-item questionnaire in conjunction with a comprehensive clinical examination, which included assessment of best corrected visual acuity (BCVA), the magnification power required for reading, use of low-vision aids and reading speed. Patients rated the extent to which low vision restricted their ability to read and participate in other activities that affect quality of life. Responses were scored on a scale of 1.0 (optimum self-evaluation) to 5.0 (very poor). In the operated eye, overall mean postoperative BCVA (distance) was not significantly better than mean preoperative BCVA (0.11 +/- 0.06 and 0.15 +/- 0.08, respectively; p = 0.53). However, 53% of patients reported a subjective increase in visual function after treatment. At the final visit, the mean magnification required was x 7.7 +/- 6.7. A total of 60% of patients needed optical magnifiers for reading and in 40% of patients closed-circuit TV systems were necessary. All patients were able to read newspaper print using adapted low-vision aids at a mean reading speed of 71 +/- 40 words per minute. Mean self-reported scores were 3.2 +/- 1.1 for reading, 2.5 +/- 0.7 for day-to-day activities and 2.7 +/- 3.0 for outdoor walking and using steps or stairs. Patients' levels of dependency were significantly correlated with scores for reading (p = 0.01), day-to-day activities (p vision-related quality of life in patients after

  17. Making mobility-related disability better: a complex response to a complex problem

    2012-10-01

    Full Text Available Abstract Mobility disability in older adults can arise from single system problems, such as discrete musculoskeletal injury. In frail older adults, however, mobility disability is part of a complex web of problems. The approach to their rehabilitation must take that complexity into account, as is reported by Fairhall et al. First, their overall health state must be assessed, which is achieved by a comprehensive geriatric assessment. The assessment can show how a particular patient came to be disabled, so that an individualized care plan can be worked out. Whether this approach works in general can be evaluated by looking at group differences in mean mobility test scores. Knowing whether it has worked in the individual patient requires an individualized measure. This is because not every patient starts from the same point, and not every patient achieves success by aiming for the same goal. For one patient, walking unassisted for three metres would be a triumph; for another it would be a tragedy. Unless we understand the complexity of the needs of frail older adults, we will neither be able to treat them effectively nor evaluate our efforts sensibly.

  19. Disruption of the IS6-AID linker affects voltage-gated calcium channel inactivation and facilitation.

    Findeisen, Felix; Minor, Daniel L

    2009-03-01

    Two processes dominate voltage-gated calcium channel (Ca(V)) inactivation: voltage-dependent inactivation (VDI) and calcium-dependent inactivation (CDI). The Ca(V)beta/Ca(V)alpha(1)-I-II loop and Ca(2+)/calmodulin (CaM)/Ca(V)alpha(1)-C-terminal tail complexes have been shown to modulate each, respectively. Nevertheless, how each complex couples to the pore and whether each affects inactivation independently have remained unresolved. Here, we demonstrate that the IS6-alpha-interaction domain (AID) linker provides a rigid connection between the pore and Ca(V)beta/I-II loop complex by showing that IS6-AID linker polyglycine mutations accelerate Ca(V)1.2 (L-type) and Ca(V)2.1 (P/Q-type) VDI. Remarkably, mutations that either break the rigid IS6-AID linker connection or disrupt Ca(V)beta/I-II association sharply decelerate CDI and reduce a second Ca(2+)/CaM/Ca(V)alpha(1)-C-terminal-mediated process known as calcium-dependent facilitation. Collectively, the data strongly suggest that components traditionally associated solely with VDI, Ca(V)beta and the IS6-AID linker, are essential for calcium-dependent modulation, and that both Ca(V)beta-dependent and CaM-dependent components couple to the pore by a common mechanism requiring Ca(V)beta and an intact IS6-AID linker.

    Zinc oxide (ZnO) is a wide band gap semiconductor and a potential candidate for next generation white solid state lighting applications. In this work, hydrogen-related complexes in lithium diffused ZnO single crystals were studied. In addition to the well-known Li-OH complex, several other hydrogen defects were observed. When a mixture of Li{sub 2}O and ZnO is used as the dopant source, zinc vacancies are suppressed and the bulk Li concentration is very high (>10{sup 19 }cm{sup −3}). In that case, the predominant hydrogen complex has a vibrational frequency of 3677 cm{sup −1}, attributed to surface O-H species. When Li{sub 2}CO{sub 3} is used, a structured blue luminescence band and O-H mode at 3327 cm{sup −1} are observed at 10 K. These observations, along with positron annihilation measurements, suggest a zinc vacancy–hydrogen complex, with an acceptor level ∼0.3 eV above the valence-band maximum. This relatively shallow acceptor could be beneficial for p-type ZnO.

    Proactive interference (PI) is the capacity to resist interference to the acquisition of new memories from information stored in the long-term memory. Previous research has shown that PI correlates significantly with the speech-in-noise recognition scores of younger adults with normal hearing. In this study, we report the results of an experiment designed to investigate the extent to which tests of visual PI relate to the speech-in-noise recognition scores of older adults with hearing loss, in aided and unaided conditions. The results suggest that measures of PI correlate significantly with speech-in-noise recognition only in the unaided condition. Furthermore the relation between PI and speech-in-noise recognition differs to that observed in younger listeners without hearing loss. The findings suggest that the relation between PI tests and the speech-in-noise recognition scores of older adults with hearing loss relates to capability of the test to index cognitive flexibility.

  6. How to develop a company AIDS policy.

    1986-07-01

    It is for most businesses only a matter of time before they will have experience with Acquired Immune Deficiency Syndrome (AIDS), and the experience could be very costly for companies which fail to implement an effective AIDS policy. Potential AIDS problems include: antidiscrimination suits based on firing or failing to hire an individual who had AIDS or carries the AIDS virus antibodies; defamation suits from employees who are wrongly identified; disability claims that do not fit the pattern for other diseases; civil rights penalties in some situations when AIDS victims are prevented from working; and run-ins with the Occupational Safety and Health Administration or the National Labor Relations Board if healthy workers refuse to work alongside AIDS victims. A company needs to think through its AIDS policy, but that does not mean establishing a "special" AIDS policy which may create paranoia among employees. The best approach is to develop a health policy that includes all catastrophic illnesses, not just AIDS. There have been few court decisions involving AIDS because AIDS is a recent illness, victims often do not live long enough to pursue the matter, and it often pays to settle AIDS cases out of court. Employers need to know that judges, administrative agencies, and arbitrators take the position that AIDS is a disability. As such, AIDS is treated under the anti-handicap discrimination laws on the books of most states. Additionally, the Federal Rehabilitation Act of 1973 prohibits discrimination against the disabled by companies that contract with the federal government or receive federal financial assistance. It usually is illegal to discriminate against the disabled workers, and in some states against workers who are perceived to have a disability. The best defense against the fear of working alongside and AIDs sufferer is education.

    2010-09-01

    Previous work has focused on HIV prevalence among forestry workers and the impact of HIV/AIDS on the sustainability of forest resources. Following a review of work examining the impacts of HIV/AIDS on the South African economy, this article presents original qualitative research examining the responses of company management to the HIV epidemic across a range of enterprises in the South African forestry industry, including large companies, contractors and cooperatives. At the level of the enterprise, management occupies a critical nexus, at which the intersecting requirements of complex government legislation, the wellbeing of workers and the demands of the business must be met. The research demonstrates that large forestry companies tend to provide only a small fraction of their workforces with HIV/AIDS education, prevention or treatment services, as they have essentially outsourced the requirement through the use of labour-supply contractors who, by and large, provide workers with scant HIV/AIDS-related programmes or benefits. Moreover, the extent to which the different types of forestry enterprises incorporate the management of HIV/AIDS in the workforce with the management of the business is highly variable, and in most instances falls short of legislative requirements that have been in place for over a decade. The implications of this for the forestry industry in South Africa are acute.

  8. On El Naschie's complex time, Hawking's imaginary time and special relativity

    International Nuclear Information System (INIS)

    Mejias, Antonio; Di Sigalotti, Leonardo G.; Sira, Eloy; De Felice, Fernando

    2004-01-01

    The idea of complex time, as first proposed by El Naschie in 1995, not only provided a very important mathematical utility in clarifying the nature of nowness, but also opened a definite possibility for the instantaneous transmission of information through the theoretical prediction of massless particles travelling at velocities larger than the speed of light. Based on a very simple thought experiment, here we show that the complex nature of time arises when two independent inertial observers, in relative uniform motion, communicate via a light signal in order to compare their own proper time measurements for the same event. The observation that the time employed by the signal to go from one observer to the other is calculable, but not measurable, permits to build up a general expression for the complex time, which not only complies with the possibility of time decomposition into two dimensions, but also conciliates with the idea of a complex space. In particular, we find that El Naschie's complex time can be interpreted as an asymptotic limit when the velocity of the moving observer equals that of light. Within this new formulation, the inverse Lorentz transformations of special relativity follow as a direct consequence of the complex time

    This stakeholder assessment of HIV/AIDS service providing institutions in Argentina offers insights into the HIV/AIDS crisis in Spanish-speaking Latin America from an institutional level and makes recommendations for strengthening the work and functioning of these institutions. This stakeholder assessment was conducted to determine how HIV/AIDS prevention and management in Argentina affects and is affected by relevant HIV/AIDS institutions. Semi-structured qualitative interviews were conducted with 13 key leaders of organizations working in HIV/AIDS prevention in Buenos Aires including non-governmental, governmental, and academic institutions. Analyses of interviewee comments are presented according to four major themes: network connections, program resources, perceptions of success, and challenges. Key findings include the need for strengthening formal networks, increasing the involvement of other non-AIDS related social institutions in promoting HIV prevention, finding more sustainable funding options, working more effectively with the public sector to create policies and regulations favorable to the HIV/AIDS field, and addressing the lack of perceived susceptibility to HIV/AIDS in Argentine culture. From leaders' comments, recommendations are made for strengthening the HIV/AIDS network among key institutions including adapting the UNAIDS "Three Ones" principal to create one crosssector office responsible for coordinating HIV/AIDS work, formalizing agreements with institutions outside of Buenos Aires, increasing the role of schools in HIV/AIDS awareness, and designing programs that address lack of perceived susceptibility to HIV/AIDS among Argentines.

    Highlights: • The relation between task complexity and the variability of procedure progression was investigated. • The two quantitative measures, TACOM and VPP, were applied to this study. • The task complexity was positively related with the operator’s procedural variability. • The VPP measure can be useful for explaining the operator’s behaviors. - Abstract: In this study, the relation between task complexity and variability of procedure progression during an emergency operation was investigated by comparing the two quantitative measures. To this end, the TACOM measure and VPP measure were applied to evaluate the complexity of tasks and variability of procedure progression, respectively. The TACOM scores and VPP scores were obtained for 60 tasks in the OPERA database, and a correlation analysis between two measures and a multiple regression analysis between the sub-measures of the TACOM measure and VPP measure were conducted. The results showed that the TACOM measure is positively associated with the VPP measure, and the abstraction hierarchy complexity mainly affected the variability among the sub-measures of TACOM. From these findings, it was discussed that the task complexity is related to an operator’s procedural variability and VPP measure can be useful for explaining the operator’s behaviors

    Lymphoma is frequently present in patients with acquired immunodeficiency (AIDS). But unlike in the general population, the appearance of lymphoma in patients with AIDS is extremely varied. The computed tomographic scans, chest radiographs, and subsequent hospital courses of 15 patients with AIDS-related lymphoma are presented. The patients presented with isolated pleural effusion (six patients), pleural and pericardial effusion (one patient), pulmonary infiltrates (five patients), and mediastinal adenopathy (three patients). This varied manner of presentation of lymphoma in AIDS patients should be recognized if diagnosis is to be made in the earlier stages of presentation

    Full Text Available This article has two main aims: to provide data on the cost of HIV/AIDS to urban South African households and to contribute to the development of a methodology that could be used in later studies. Data on the costs of HIV/AIDS-related morbidity and mortality were collected from a purposively selected sample of households in Soweto on four occasions between September 2002 and August 2003. The sample comprised 61 affected households, which had at least one member with a CD4 count of 200 or less at the start of the study, and 52 non-affected households. Three types of costs were examined – financial, economic and the present value of lost future earnings. The data suggest that the financial costs of morbidity and mortality were three and two times greater, respectively, for affected households than for those non-affected households that reported disease and/or death. Mortality costs far exceeded morbidity costs. The present value of lost future earnings, where the deceased had previously been an income earner, proved to be the major cost incurred by an affected household.

    Computer based method can help in discovery of leads and can potentially eliminate chemical synthesis and screening of many irrelevant compounds, and in this way, it save time as well as cost. Molecular modeling systems are powerful tools for building, visualizing, analyzing and storing models of complex molecular structure that can help to interpretate structure activity relationship. The use of various techniques of molecular mechanics and dynamics and software in Computer aided drug design along with statistics analysis is powerful tool for the medicinal chemistry to synthesis therapeutic and effective drugs with minimum side effect.

    Health-related quality of life (HRQoL) is a broad concept reflecting a patient's general subjective perception of the effect of an illness or intervention on physical, psychological and social aspects of their daily life. HRQoL among patients infected with HIV has become an important indicator of impact of disease and treatment outcomes. A cross-sectional survey was carried out at Chitungwiza Central Hospital, Zimbabwe, to assess HRQoL in patients with HIV/AIDS receiving antiretroviral therapy (ART), using two validated instruments. The HIV/AIDS-targeted quality of life (HAT-QoL) and EuroQoL Five-dimensions-Three-level (EQ-5D-3L) instruments were used to assess HRQoL. Internal consistency reliability and convergent validity of the two instruments were also evaluated. For construct validity, the relationships between HRQoL scores and socio-economic and HIV/AIDS-related characteristics were explored. The median scores for the HAT-QoL dimensions ranged from 33.3 (financial worries) to 100 (HIV mastery). A considerably low HAT-QoL dimension score of 50.0 was observed for sexual function. There were ceiling effects for all HAT-QoL dimension scores except for financial worries and disclosure worries. Floor effects were observed for financial worries and sexual function. The median of the EQ-5D-3L index and visual analogue scale (VAS) was 0.81 and 79.0, respectively. There were no floor or ceiling effects for both the EQ-5D-3L index and VAS. The overall scale Cronbach's alpha was 0.83 for HAT-Qol and 0.67 for EQ-5D-3L. HAT-QoL demonstrated good convergent validity with EQ-5D index (0.58) and VAS (0.40). A higher level of HRQoL was positively and significantly related to income, education and employment. The patients' self-reported HRQoL was generally satisfactory in all the HAT-QoL dimensions as well as the two components on the EQ-5D-3L instrument. The two instruments demonstrated good measurement properties in HIV/AIDS patients receiving ART and have potential for use

    Activation-induced cytidine deaminase (AID) converts cytidine to uridine at Immunoglobulin (Ig) loci, initiating somatic hypermutation and class switching of antibodies. In vitro, AID acts on single stranded DNA (ssDNA), but neither double-stranded DNA (dsDNA) oligonucleotides nor RNA, and it is believed that transcription is the in vivo generator of ssDNA targeted by AID. It is also known that the Ig loci, particularly the switch (S) regions targeted by AID are rich in transcription-generated DNA/RNA hybrids. Here, we examined the binding and catalytic behavior of purified AID on DNA/RNA hybrid substrates bearing either random sequences or GC-rich sequences simulating Ig S regions. If substrates were made up of a random sequence, AID preferred substrates composed entirely of DNA over DNA/RNA hybrids. In contrast, if substrates were composed of S region sequences, AID preferred to mutate DNA/RNA hybrids over substrates composed entirely of DNA. Accordingly, AID exhibited a significantly higher affinity for binding DNA/RNA hybrid substrates composed specifically of S region sequences, than any other substrates composed of DNA. Thus, in the absence of any other cellular processes or factors, AID itself favors binding and mutating DNA/RNA hybrids composed of S region sequences. AID:DNA/RNA complex formation and supporting mutational analyses suggest that recognition of DNA/RNA hybrids is an inherent structural property of AID. Copyright © 2017 Elsevier Ltd.

    Full Text Available AIDS morbidity and mortality are expected to have a large impact on households' labor supply in rural Malawi since they reduce the time that adults can spend on production for subsistence and on income generating activities. However, the data demands for estimating this impact are high, limiting the amount of empirical evidence. In this paper, we utilize a unique combination of quantitative and qualitative data, including biomarkers for HIV, collected by the Malawi Diffusion and Ideational Change Project, to analyze the impact of AIDS-related morbidity and mortality on time allocation decisions for rural Malawians. We evaluate both the direct effect of HIV/AIDS on the time allocation of affected individuals as well as its indirect effect on the time allocation of surviving household members. We find that the latter is the most important effect of AIDS-related morbidity and mortality, especially on women's time. Specifically, AIDS induces diversification of income sources, with women reallocating their time from work-intensive (typically farming and heavy chores to cash-generating tasks (such as casual labor.

  17. AID as Gift: an initial approach

    2008-01-01

    Full Text Available The article proposes that some of the key practices in the area of international cooperation for development can be better understood in terms of a gift regime. To this end, it compares ethnographic data relating to the modus operandi of the aid sector in East Timor with the legacies of Marcel Mauss and the recent production of M.A.U.S.S. International aid policies are shown to be important means for establishing hegemony in glocal negotiation spaces in which different actors construct identities and relations of alliance, honor and precedence. In this debate, it is argued that East Timor's biggest counter-gift to the international community has been to function as an instrument through which values cherished by aid donors, expressed in Western myths of good society, can once again be cultivated in the process of building a new national state.

    This paper is an approach to AIDS as a topic among a drug abusers sample of the city of Buenos Aires. Research was carried out on the basis of a qualitative methodology. In an attempt at surveying opinions and attitudes of such a sample as regards AIDS (i.e. subjects' cognitive map), 21 drug abusers from three different rehabilitation programs operating in the B.A. area were interviewed. On the basis of the research performed, the authors elaborate communication strategies among drug abusers that would be helpful for authorities engaged in AIDS prevention to adopt. To boost a strategy likely to break up the AIDS-drug association existing in the mind of many an abuser would be highly advisable so that a separation be settled between both representations, thus giving drug abusers a higher motivation for self-care practice.

    Stigma is commonly experienced by people living with HIV/AIDS and by those providing care to HIV/AIDS patients. Few intervention studies have explored the impact of workplace policies and/or quality improvement on stigma. We examine the contribution of health care workplace policies, procedures and quality assurance initiatives, and self- and peer-assessed individual nurse practices, to nurse-reported HIV/AIDS-stigma practices toward patients living with HIV/AIDS and nurses in health care settings. Our sample of survey respondents (n = 1157) included managers (n = 392) and registered/enrolled nurses (n = 765) from 29 facilities in 4 countries (South Africa, Uganda, Jamaica, Kenya). This is one of the first studies in LMIC countries to use hierarchical linear modeling to examine the contributions of organizational and individual factors to HIV/AIDS stigma. Based on our results, we argue that organizational interventions explicitly targeting HIV/AIDS stigma are required to reduce the incidence, prevalence and morbidity of HIV/AIDS.

    To quantify expressed stigma in clients of the Kangemi program for HIV+ children, and to characterize the association between stigma and other population characteristics. By means of a household survey we created a stigma index and indices for other social and knowledge domains that influence HIV-related healthcare. We used chi2, anova, and correlation to identify associations between domains. The mean (+/-SD) expressed stigma on a six points scale (6 = least stigma) was 3.65 +/- 1.64. Composite scores on knowledge about AIDS were skewed toward more knowledge; and analysis of individual knowledge items indicates that most respondents reject erroneous traditional beliefs and myths about the causes and transmission routes of AIDS. Respondents who were younger, had never married, and had less education expressed greater stigma. Differences in stigma were associated with poor knowledge about AIDS and negative attitudes toward testing, but not with gender or tribal affiliation. Condom use at last intercourse, unrelated to stigma, was only 40% (n = 218). While this population has good knowledge about AIDS and appraises risks realistically, it fails to reduce these risks. Associations between stigma and other domains can inform interventions that improve HIV care and mitigate spread of HIV.

    The complexity of providing healthcare to people with HIV/Aids requires investment in comprehensive action and care, constituting a challenge for the multidisciplinary work teams to build an interdisciplinary practice. This study sought to analyze comprehensive healthcare in the Specialized Assistance Services for HIV/Aids (SAE-HIV/Aids) in Recife, in the State of Pernambuco, starting with the process and organization of team work. This is a case study developed in three SAE-HIV/Aids units, based on a qualitative approach using different research techniques. The results show that SAE-HIV/Aids have complied with most of the Brazilian Health Ministry recommendations in terms of basic infrastructure, though none of them had a team of appropriate size. These services have shown signs of fragmentation and difficulty in establishing a systematic intersectorial and interdisciplinary practice, with failings in ensuring the reference and counter-reference flow. It was seen that there was little appreciation of the role of the manager as team leader. The need to perceive the user as a whole was identified, as well as for the team to work in a coordinated manner in order to ensure communicative and relational activities.

    To analyze the ultrasonography findings in abdomen in the AIDS patients in our hospital, as well as the indications for this exploration, assessing the role of abdominal ultrasound (AU). The ultrasonographic and clinical findings in 527 patients who underwent a total of 715 explorations between 1992 and 1996 were studied. Hepatomegaly and/or splenomegaly, usually homogeneous, were observed in nearly half of the studies (45%); one third of the patients with marked splenomegaly presented visceral leishmaniasis. Focal lesions in liver and/or spleen, corresponding to angiomas, abscesses, lymphomatous lesions and metastasis, were detected in 5.7% of the explorations. Thirty-five percent of the AU revealed the presence of lymphadenopathy; nodes measuring over 2.5 cm were usually related to potential treatable infection or neoplasm. Thickening of the gallbladder wall did not usually indicate the presence of acute cholecystitis unless Murphy''s sign was also detected. Bile duct dilation and wall thickening was related to opportunistic cholangitis, and the increase in the echogenicity of the renal parenchyma was linked to AIDS-related nephropathy. Despite the fact that many of findings with AU are nonspecific, we consider that this approach should be the principal diagnostic technique in AIDS patients with suspected abdominal pathology or fever of unknown origin.

    This research examines young unmarried women's ways of talking about AIDS, AIDS prevention, and its relationship to mass media AIDS messages in Thailand. Data were derived from a survey conducted in four districts of Kanchanaburi province. Three hundred ninety-seven unmarried women were extracted from the approximately 1,800 original subjects for this analysis. Respondents were asked about the subjects and extent of their conversations about AIDS, the choice of discussion partners, considerations of social appropriateness in talking about the disease, as well as their risk perception. Important findings were that (a) women tend to talk about AIDS primarily with friends and siblings, (b) their reception level of mass media messages is related to the number of topics discussed and frequency of talks by the subjects, and (c) socioeconomic status and age are related to the variety and frequency of talking about AIDS. Implications for AIDS education are discussed.

    With a population of only 1.3 million, Botswana relies heavily upon imported skilled labor and management. Officially, all forms of discrimination based upon a citizen's HIV/AIDS status are illegal in Botswana. The government, however, screens all expatriates considered for contractual jobs with the state, and does not employ HIV-seropositive candidates. Recent government efforts to train local people to replace expatriates and diversify and expand the economy by supporting local business and encouraging foreign investment may, however, be seriously jeopardized by the HIV/AIDS epidemic. The development and implementation of prevention and coping strategies, especially at the workplace, have been slow even though AIDS-in-the-Workplace program materials, including videos, posters, brochures, and condoms, are provided free of charge. The lack of a clear understanding by senior management of the legal and financial ramifications of the HIV/AIDS epidemic is one reason for the widespread nonuse by companies of the materials. AIDSCAP in Botswana recently reviewed the activities of four companies which had, however, developed model AIDS-in-the-Workplace programs. Three of the companies chose a peer education model, holding regular formal education sessions as well as informal small group sessions run by peer educators. The peer educators have as much time during their work day as they need to work upon HIV/AIDS activities. The other company has a health department which holds a formal prevention education session for all employees yearly, while clinics in the on-site employee housing complex provide continuous information on women's health, prenatal and infant care as it relates to HIV/AIDS, and negotiating safer sex. Management reports that employees seem to have responded well to the programs, but changing their attitudes toward infected colleagues is proving more difficult. The author notes that managers over time will also have to begin thinking about training

    AIDS-related stigma is a major contributor to the health and psychosocial well-being of children affected by AIDS. Whilst it is often suggested that AIDS-affected children may be stigmatised by other children, to date no research focuses specifically on child-on-child stigma. Using social representations theory, we explore how Zimbabwean children represent AIDS-affected peers, examining (i) whether or not they stigmatise, (ii) the forms stigma takes, and (iii) the existence of non-stigmatising representations that might serve as resources for stigma-reduction interventions. Our interest in identifying both stigmatising and non-stigmatising representations is informed by a theory of change which accords a central role to community-level debate and dialogue in challenging and reframing stigmatising representations. In late 2008, 50 children (aged 10-12) were asked to "draw a picture of a child whose family has been affected by AIDS in any way", and to write short stories about their drawings. Thematic analysis of stories and drawings revealed frequent references to stigmatisation of AIDS-affected children--with other children refusing to play with them, generally keeping their distance and bullying them. However children also frequently showed a degree of empathy and respect for AIDS-affected children's caring roles and for their love and concern for their AIDS-infected parents. We argue that a key strategy for stigma-reduction interventions is to open up social spaces in which group members (in this case children) can identify the diverse and contradictory ways they view a stigmatised out-group, providing opportunities for them to exercise agency in collectively challenging and renegotiating negative representations. Contrary to the common view that drawings enable children to achieve greater emotional expression than written stories, our children's drawings tended to be comparatively stereotypical and normative. It was in written stories that children most

    Sexual transmission of HIV/AIDS among women is growing in the Middle East region. Despite the fact that there are numerous gender-related sociocultural factors influencing HIV/AIDS protective behaviors, little gender-specificity is carried out in HIV prevention in Iran. In order to close this gap, we aimed to provide preliminary work that explored the perceptions that women at risk of HIV had about gender norms and gendered power and their ability to protect themselves against HIV/AIDS. Twenty-five semi-structured in-depth interviews were conducted with women at risk of HIV/AIDS, aged 21-49 years, at Voluntary Counseling and Testing Centers or Drop in Centers in Tehran, Iran. Results showed that perceived gender norms were essential barriers of protective behavior through sexual socialization, male control over condom use and sexual decision-making, male pleasure predominating in sexual encounters and sexual double standards, and economic dependencies. In the conclusions, we consider how HIV/AIDS preventive programs can be structured to be gender-sensitive and empowering in Iran.

    Since nutrition can influence the process of carcinogenesis, this study's objectives are to review the relationship between nutrition and cancer from the point of view of the role of micronutrients in the treatment of cancer patients, and to get to know the deficit relationship and the excess of micronutrients, with the etiology and cancer treatment. At the same time the patient's weight loss relates, among other things, to the type of cancerous tumor, its location, stage thereof, reason for which it may be associated with the deficiency of macro and micronutrients as from psychogenic, anorectics and mal-absorption effects or with mechanical effects as obstruction, among other toxic effects that are common in the treatment of cancer. Hence, the importance that the nutrition expert must have in making an adequate overall nutritional evaluation that allows the nutritional diagnosis, in studying the dietary patterns, to determine the toxic effects of the antineoplastic treatment in order to handle the treatment's timing excellence, symptoms and signs, and thus act effectively optiimizing the patient's life quality, and therewith his/her survival. There are controversies as to which specific dietary factors are related to cancer etiology and the results of studies on metabolic factors, and therefore, the relationship Cancer-Nutrition is quiet complex.

    The biological behavior of chronic lymphocytic leukemia and small lymphocytic lymphoma is unpredictable. Nonetheless, non-mutated IgV(H) gene rearrangement, ATM (11q22-23) and p53 (17p13) deletion are recognized as unfavorable prognosticators in chronic lymphocytic leukemia. The mRNA expression of activation-induced cytidine deaminase (AID), an enzyme indispensable for somatic hypermutation processes, was claimed to be predictive of non-mutated chronic lymphocytic leukemia cells in blood. Here, we evaluated AID protein expression compared with known molecular and immunohistochemical prognostic indicators in 71 chronic lymphocytic leukemia/small lymphocytic lymphoma patients using a tissue microarray approach. We found AID heterogeneously expressed in tumor cells as shown by colocalization analysis for CD5 and CD23. Ki-67 positive paraimmunoblasts of the proliferation centers displayed the highest expression. This observation is reflected by a significant association of AID positivity with a high proliferation rate (P=0.012). ATM deletion was detected in 10% (6/63) of patients and p53 deletion in 19% (13/67) of patients. Moreover, both ATM (P=0.002) and p53 deletion (P=0.004) were significantly associated with AID. IgV(H) gene mutation was seen in 45% (27/60) of patients. Twenty-five percent (17/69) of patients with AID-positive chronic lymphocytic leukemia/small lymphocytic lymphoma displayed a shorter survival than AID-negative chronic lymphocytic leukemia/small lymphocytic lymphoma patients (61 vs 130 months, P=0.001). Although there was a trend, we could not show an association with the IgV(H) gene mutation status. Taken together, our study shows that AID expression is an indicator of an unfavorable prognosis in chronic lymphocytic leukemia/small lymphocytic lymphoma patients, although it is not a surrogate marker for the IgV(H) status. Furthermore, the microenvironment of proliferation centers seems to influence AID regulation and might be an initiating factor

    We reviewed the literature to determine the effectiveness of HIV-related interventions in reducing HIV/AIDS stigma. Studies selected had randomized controlled trial (RCT), pretest–posttest with a non-randomized control group, or pretest–posttest one group study designs in which HIV-related interventions were being evaluated, and in which HIV/AIDS stigma was one of the outcomes being measured. A checklist was used to extract data from accepted studies, assess their internal validity, and overall quality. Data were extracted from 19 studies, and 14 of these studies demonstrated effectiveness in reducing HIV/ AIDS stigma. Only 2 of these 14 effective studies were considered good studies, based on quality, the extent to which the intervention focused on reducing HIV/AIDS stigma, and the statistics reported to demonstrate effectiveness. Future studies to reduce HIV/AIDS stigma could improve by designing interventions that pay greater attention to internal validity, use validated HIV/AIDS stigma instruments, and achieve both statistical and public health significance.

    2005-08-01

    HIV/AIDS is a global problem with an estimated 40 million infected people. In less than two years, this figure will leap to 100 million according to the World Health Organisation (WHO). By 2005, 65 million people will be infected. Half of the number of people in this group will be under 25 years old, and will die before they reach the age of 35. In a South African study done by the Human Science Research Council and published in 2003, regarding the impact of HIV/AIDS on the health sector, the findings were that 15% of health workers in public and private hospitals tested positive for HIV antibodies. Together with these facts above it was found that 46.2 percent of patients served in medical and paediatric wards tested positive for HIV. These factors have major implication for staffing in the future and the role of the nurse manager in South Africa. To explore the management of HIV/AIDS in the workplace of nurses in selected health services in KwaZulu-Natal. This research was part of a greater study on the exploration of the presence of caring as part of nursing management. THE METHODOLOGY: The qualitative research approach was used with a phenomenological design, which ensured that the richness and the complexities are reflected in the study. The data was collected by means of an open-ended question to nurse managers during an interview. The first question posed was; How do you or your services care for nurses in this hospital? Secondly nurse managers were asked, To explain their role in caring for HIV/AIDS positive nurses on their staff establishment. A qualitative analysis of the interviews with nurse managers indicated that they rate HIV/AIDS issues as an important part of their management task. Four main themes were identified, namely HIV/AIDS, counselling, dying of AIDS and funerals. Rich descriptions of these themes are given in this paper. Nurse managers in the health services are managing HIV/AIDS affected nurses, but are doing so without any formal policy

    Full Text Available In order to model multi-dimensions and multi-granularities oriented complex systems, this paper firstly proposes a kind of multi-relational Fuzzy Cognitive Map (FCM to simulate the multi-relational system and its auto construct algorithm integrating Nonlinear Hebbian Learning (NHL and Real Code Genetic Algorithm (RCGA. The multi-relational FCM fits to model the complex system with multi-dimensions and multi-granularities. The auto construct algorithm can learn the multi-relational FCM from multi-relational data resources to eliminate human intervention. The Multi-Relational Data Mining (MRDM algorithm integrates multi-instance oriented NHL and RCGA of FCM. NHL is extended to mine the causal relationships between coarse-granularity concept and its fined-granularity concepts driven by multi-instances in the multi-relational system. RCGA is used to establish high-quality high-level FCM driven by data. The multi-relational FCM and the integrating algorithm have been applied in complex system of Mutagenesis. The experiment demonstrates not only that they get better classification accuracy, but it also shows the causal relationships among the concepts of the system.

  14. Task Complexity Modulates Sleep-Related Offline Learning in Sequential Motor Skills

    Directory of Open Access Journals (Sweden)

    Klaus Blischke

    2017-07-01

    Full Text Available Recently, a number of authors have advocated the introduction of gross motor tasks into research on sleep-related motor offline learning. Such tasks are often designed to be more complex than traditional key-pressing tasks. However, until now, little effort has been undertaken to scrutinize the role of task complexity in any systematic way. Therefore, the effect of task complexity on the consolidation of gross motor sequence memory was examined by our group in a series of three experiments. Criterion tasks always required participants to produce unrestrained arm movement sequences by successively fitting a small peg into target holes on a pegboard. The sequences always followed a certain spatial pattern in the horizontal plane. The targets were visualized prior to each transport movement on a computer screen. The tasks differed with respect to sequence length and structural complexity. In each experiment, half of the participants initially learned the task in the morning and were retested 12 h later following a wake retention interval. The other half of the subjects underwent practice in the evening and was retested 12 h later following a night of sleep. The dependent variables were the error rate and total sequence execution time (inverse to the sequence execution speed. Performance generally improved during acquisition. The error rate was always low and remained stable during retention. The sequence execution time significantly decreased again following sleep but not after waking when the sequence length was long and structural complexity was high. However, sleep-related offline improvements were absent when the sequence length was short or when subjects performed a highly regular movement pattern. It is assumed that the occurrence of sleep-related offline performance improvements in sequential motor tasks is associated with a sufficient amount of motor task complexity.

    Chemoinformatics approaches open new opportunities for computer-aided design of new efficient metal binders. Here, we demonstrate performances of ISIDA and COMET software tools to predict stability constants (log K) of the metal ion/organic ligand complexes in solution and to design in silico new molecules possessing desirable properties. The predictive models for log K of lanthanides complexation in water have been developed. Some new uranyl binders based on monoamides and on phosphoryl-containing podands were suggested theoretically, then synthesized and tested experimentally. Reasonable agreement between experimental uranyl distribution coefficients and theoretically predicted values has been observed. (orig.)

    The aim of the present work was to develop further the flotation method for separating RE ions, namely, to examine the possibility of separating Re ions by converting them into citrate complexes and subsequently binding them with the aid of hexadecylamine in difficultly soluble and easily floatable compounds, sublates. Thus, these investigations showed that it is possible in principle to separate RE ions by conversion into citrate complexes followed by flotation separation of the latter from solutions with the aid of hexadecylamine

    To investigate clinical manifestations and diagnostic difficulties in patients with HIV/AIDS in the practice of therapeutic units of a multidisciplinary hospital. The investigation included 65 HIV/AIDS patients admitted to the therapy units of a Saratov Regional clinical hospital in 2007 to 2011. The clinical features of HIV/AIDS, immunological status, and viral load were studied. The structure of the clinical manifestation of HIV/AIDS showed a preponderance of lung injury in 45 (69%) patients. There were hematological disorders in 38 (58%) patients and nephropathy in 33 (51 %); 11 (17%) patients were diagnosed with infective endocarditis. Rheumatic symptoms and syndromes mimicking HIV/AIDS were found in 10 (15.4%) patients. The degree of immune disorders was most severe in patients with pulmonary dissemination and rheumatic masks and mutually related to the rate of cutaneous manifestations. The specific features of lung injury, infective endocarditis, pulmonary hypertension, rheumatic symptoms, and kidney injury were discussed in HIV/AIDS patients having different causes for admission to specialized therapy units. In connection with the clinical polymorphism of HIV/AIDS, physicians of all specialties should be alert for the possible clinical manifestations of this disease to timely examine patients.

    Young men who have sex with men (YMSM) have become high risk groups for HIV infection in China. Recent researches suggest that sexual sensation seeking is significantly associated with AIDS-related knowledge, attitudes and behaviors, but the relationship is not clear in the field of YMSM in China. The present study aimed to evaluate the relationship between sexual sensation seeking and AIDS-related knowledge, attitudes, and behaviors among YMSM in China. A cross-sectional study was conducted in Wuhan, China from May to November 2013. 403 YMSM were recruited and 373 of them completed the questionnaire. Regression analyses indicated that YMSM with high sexual sensation seeking score are more likely to have low awareness of knowledge and negative attitude about condom use, as well as more risky sexual behaviors.

    At present, cad/cam (computer-aided design and manufacture) have fine wider and wider application in mechanical industry. For the complex surfaces, the traditional machine tool can no longer satisfy the requirement of such complex task. Only by the help of cad/cam can fulfill the requirement. The machining of the vane surface of the impeller leaf has been considered as the hardest challenge. Because of their complex shape, the 5-axis cnc machine tool is needed for the machining of such parts. The material is hard to cut, the requirement for the surface finish and clearance is very high, so that the manufacture quality of impeller leaf represent the level of 5-axis machining. This paper opened a new field in machining the complicated surface, based on a relatively more rigid mathematical basis. The theory presented here is relatively more systematical. Since the lack of theoretical guidance, in the former research, people have to try in machining many times. Such case will be changed. The movement of the cutter determined by this method is definite, and the residual is the smallest while the times of travel is the fewest. The criterion is simple and the calculation is easy.

    HIV has been spreading over the territories of our countries for 18 years, and it is still possible to resist the epidemic in a unique and efficient way. In June 2001, the UNO General Assembly Special Session was devoted to the problem of HIV/AIDS in full. Its Declaration of Commitment on HIV/AIDS (Resolution S-26/2) defines main directions of this work both in world-wide, regional, and international scopes. It should be stressed that first of all the Declaration emphasizes the necessity to improve management and coordination of efforts at the global, regional, and national levels, which is of special importance to Eastern Europe and Central Asia, where a new phase of HIV infection epidemic has begun and the spread of the virus grows and very soon may gain uncontrollable character. As for the countries of our region, here the epidemic process has been developing mostly through sexual way of transmission for 8 years since 1987, when the first case of HIV infection was revealed. More than 350000 HIV-infected people, including more than 15,000 children, have been registered in Russian Federation. More than 9000 people have died. The proportion of childbearing age women constantly grows, and the number of children born to mothers with AIDS has now exceeded 15,000. To realize the component "Prevention of HIV infection, B and C hepatitis, and revealing and treatment of HIV patients" of the priority national health project, 3.1 billion rubles are allocated for the prophylaxis of and fight against HIV and AIDS. The measures that are planned to take will allow for principle changes in the present situation with medical aid providence of contemporary antiretroviral medicines. Russian Orthodox Church with its parishes, monasteries etc. carries out numerous projects of primary HIV prophylaxis among children and young people in different regions; these projects are directed towards forming moral values.

  1. Improving nuclear power plant safety through operator aids

    International Nuclear Information System (INIS)

    1987-12-01

    In October 1986, the IAEA convened a one-week Technical Committee Meeting on Improving Nuclear Power Plant Safety Through Operator Aids. The term ''operator aid'' or more formally ''operator support system'' refers to a class of devices designed to be added to a nuclear power plant control station to assist an operator in performing his job and thereby decrease the probability of operator error. The addition of a carefully planned and designed operator aid should result in an increase in nuclear power plant safety and reliability. Operator aids encompass a wide range of devices from the very simple, such as color coding a display to distinguish it out of a group of similar displays, to the very complex, such as a computer-generated video display which concentrates a number of scattered indicator readings located around a control room into a concise display in front of the operator. This report provides guidelines and information to help make a decision as to whether an operator aid is needed, what kinds of operator aids are available and whether it should be purchased or developed by the utility. In addition, a discussion is presented on advanced operator aids to provide information on what may become available in the future. The broad scope of these guidelines makes it most suitable for use by a multi-disciplinary team. The document consists of two parts. The recommendations and results of the meeting discussions are given in the first part. The second part is the annex where the papers presented at the Technical Committee Meeting are printed. A separate abstract was prepared for each of the 10 papers. Refs, figs and tabs

    Ontologies are knowledge structures that lend support to many health-information systems. A study is carried out to assess the quality of ontological concepts based on a measure of their complexity. The results show a relation between complexity of concepts and error rates of concepts. A measure of lateral complexity defined as the number of exhibited role types is used to distinguish between more complex and simpler concepts. Using a framework called an area taxonomy, a kind of abstraction network that summarizes the structural organization of an ontology, concepts are divided into two groups along these lines. Various concepts from each group are then subjected to a two-phase QA analysis to uncover and verify errors and inconsistencies in their modeling. A hierarchy of the National Cancer Institute thesaurus (NCIt) is used as our test-bed. A hypothesis pertaining to the expected error rates of the complex and simple concepts is tested. Our study was done on the NCIt's Biological Process hierarchy. Various errors, including missing roles, incorrect role targets, and incorrectly assigned roles, were discovered and verified in the two phases of our QA analysis. The overall findings confirmed our hypothesis by showing a statistically significant difference between the amounts of errors exhibited by more laterally complex concepts vis-à-vis simpler concepts. QA is an essential part of any ontology's maintenance regimen. In this paper, we reported on the results of a QA study targeting two groups of ontology concepts distinguished by their level of complexity, defined in terms of the number of exhibited role types. The study was carried out on a major component of an important ontology, the NCIt. The findings suggest that more complex concepts tend to have a higher error rate than simpler concepts. These findings can be utilized to guide ongoing efforts in ontology QA.

    A new synthesis of the principles of quantum mechanics and Relativity is proposed in the context of complex differential geometry. The positivity of the energy implies that wave functions and fields can be extended to complex spacetime, and it is shown that this complexification has a solid physical interpretation as an extended phase space. The extended fields can be said to be realistic wavelet transforms of the original fields. A new, algebraic theory of wavelets is developed.

    1992-01-01

    The Region of the Americas took part in World AIDS DAy 1991, whose theme, "Sharing the Challenge," urged all sectors of society to support AIDS-related education, services, and advocacy. The day of observance was intended to encourage the participation of public, private, nongovernmental, and religious leaders in promoting AIDS-related activities. Although World AIDS Day took place on December 1, activities in the Region of the Americans began from the last week of November and into the first week of December. Most of these activities were designed to educate the public on how to avoid infection, as well as inform and sensitize audiences on the health and social needs of those infected. These activities took the form of press conferences, exhibitions, lectures, public concerts, television adds, etc. One such activity, sponsored by the Pan American Health Organization (PAHO) and held at its headquarters in Washington, D.C., focused on the AIDS crisis and the need for educational activities. The program opened with a speech by Dr. Carlyle Guerra de Macedo, PAHO's director, who warned against complacency in confronting the disease. US Surgeon General Antonia Novello also spoke at the occasion, addressing the growing threat of AIDS among women. Already, 12% of AIDS victims in the US are women, and heterosexual transmissions of AIDS will likely continued to increase. Pointing out that a vaccine is not expected in the short term, PAHO's Dr. David Brandling-Bennet stressed that the fight against AIDS depends on disseminating information. The PAHO meeting also featured a panel discussion composed of educators and health professionals, who discussed the educational responsibility of television in transmitting the AIDS-prevention message to the public.

    Full Text Available The concepts, targets, tools, institutions and modes of operation of official development assistance have been overtaken by the pace of change in a world marked by the combined momentum of demography, technology and economic growth.Aid can however recover, as social consequences of the globalization call for new forms of regulation. It will then be necessary to modify and diversify our target-setting processes, to update operating procedures, and to find better ways of measuring policy implementation. Aid volumes will certainly continue to grow, and we must transform the way aid is financed. Public and private aid stakeholders must recognize the importance of these transformations and be ready to support them, by questioning the methods as well as the objectives of the policies they are implementing. Otherwise, they will severely impede the emergence of the policies we need if we are to build a better world.

    Activation-induced cytidine deaminase (AID), primarily expressed in activated mature B lymphocytes in germinal centers, is the key factor in adaptive immune response against foreign antigens. AID is responsible for producing high-affinity and high-specificity antibodies against an infectious agent, through the physiological DNA alteration processes of antibody genes by somatic hypermutation (SHM) and class-switch recombination (CSR) and functions by deaminating deoxycytidines (dC) to deoxyuridines (dU), thereby introducing point mutations and double-stranded chromosomal breaks (DSBs). The beneficial physiological role of AID in antibody diversification is outweighed by its detrimental role in the genesis of several chronic immune diseases, under non-physiological conditions. This review offers a comprehensive and better understanding of AID biology and its pathological aspects, as well as addresses the challenges involved in AID-related cancer therapeutics, based on various recent advances and evidence available in the literature till date. In this article, we discuss ways through which our interpretation of AID biology may reflect upon novel clinical insights, which could be successfully translated into designing clinical trials and improving patient prognosis and disease management.

    The practice of euthanasia and physician-assisted suicide (EAS) is always complex, but some cases are more complex than others. The nature of these unusually complex cases is not known. To identify and categorize the characteristics of EAS requests that are more complex than others. We held in-depth interviews with 28 Dutch physicians about their perception of complex cases of EAS requests. We also interviewed 26 relatives of patients who had died by EAS. We used open coding and inductive analysis to identify various different aspects of the complexities described by the participants. Complexities can be categorized into relational difficulties-such as miscommunication, invisible suffering, and the absence of a process of growth toward EAS-and complexities that arise from unexpected situations, such as the capricious progress of a disease or the obligation to move the patient. The interviews showed that relatives of the patient influence the process toward EAS. First, the process toward EAS may be disrupted, causing a complex situation. Second, the course of the process toward EAS is influenced not only by the patient and his/her attending physician but also by the relatives who are involved. Communicating and clarifying expectations throughout the process may help to prevent the occurrence of unusually complex situations.

    In this paper, chemometrics methods were applied to resolve the high performance liquid chromatography (HPLC) fingerprints of complex, many-component substances to compare samples from a batch from a given manufacturer, or from those of different producers. As an example of such complex substances, we used a common Chinese traditional medicine, Huoxiang Zhengqi Tincture (HZT) for this research. Twenty-one samples, each representing a separate HZT production batch from one of three manufacturers were analyzed by HPLC with the aid of a diode array detector (DAD). An Agilent Zorbax Eclipse XDB-C18 column with an Agilent Zorbax high pressure reliance cartridge guard-column were used. The mobile phase consisted of water (A) and methanol (B) with a gradient program of 25-65% (v/v, B) during 0-30min, 65-55% (v/v, B) during 30-35min and 55-100% (v/v, B) during 35-60min (flow rate, 1.0mlmin(-1); injection volume, 20mul; and column temperature-ambient). The detection wavelength was adjusted for maximum sensitivity at different time periods. A peak area matrix with 21objectsx14HPLC variables was obtained by sampling each chromatogram at 14 common retention times. Similarities were then calculated to discriminate the batch-to-batch samples and also, a more informative multi-criteria decision making methodology (MCDM), PROMETHEE and GAIA, was applied to obtain more information from the chromatograms in order to rank and compare the complex HZT profiles. The results showed that with the MCDM analysis, it was possible to match and discriminate correctly the batch samples from the three different manufacturers. Fourier transform infrared (FT-IR) spectra taken from samples from several batches were compared by the common similarity method with the HPLC results. It was found that the FT-IR spectra did not discriminate the samples from the different batches.

    Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to

    A wide range of pharmaceutical products are needed for diagnosis, treatment, and prevention of HIV/AIDS. However, interrupted supplies and stock-outs are the major challenges in the supply chain of ARV medicines and related commodities. The aim of this study was to assess the supply chain management of HIV/AIDS related commodities in public health facilities of Addis Ababa, Ethiopia. A descriptive cross-sectional survey complemented by qualitative method was conducted in 24 public health facilities (4 hospitals and 20 health centers). A semi-structured questionnaire and observation check list were used to collect data on HIV/AIDS related service, reporting and ordering; receiving, transportation and storage condition of ARV medicines and test kits; and supportive supervision and logistics management information system. In addition, in-depth interview with flexible probing techniques was used to complement the quantitative data with emphasis to the storage condition of ARV medicines and test kits. Quantitative data was analyzed using SPSS version-20. Analysis of qualitative data involved rigorous reading of transcripts in order to identify key themes and data was analyzed using thematic approach. The study revealed that 16 health centers and one hospital had recorded and reported patient medication record. Six months prior to the study, 14 health centers and 2 hospitals had stopped VCT services for one time or more. Three hospitals and 18 health centers claimed to have been able to submit the requisition and report concerning ARV medicines to Pharmaceutical Fund and Supply Agency according to the specific reporting period. More than three-fourth of the health centers had one or more emergency order of ARV medicines on the day of visit, while all of hospitals had emergency order more than 3 times within 6 months prior to the study. All of the hospitals and nearly half of the health centers had an emergency order of test kits more than 3 times in the past 6

    Background Decision aids are evidence based tools that assist patients in making informed values-based choices and supplement the patient-clinician interaction. While there is evidence to show that decision aids improve key indicators of patients' decision quality, relatively little is known about physicians' acceptance of decision aids or factors that influence their decision to use them. The purpose of this study was to describe physicians' perceptions of three decision aids, their expressed intent to use them, and their subsequent use of them. Methods We conducted a cross-sectional survey of random samples of Canadian respirologists, family physicians, and geriatricians. Three decision aids representing a range of health decisions were evaluated. The survey elicited physicians' opinions on the characteristics of the decision aid and their willingness to use it. Physicians who indicated a strong likelihood of using the decision aid were contacted three months later regarding their actual use of the decision aid. Results Of the 580 eligible physicians, 47% (n = 270) returned completed questionnaires. More than 85% of the respondents felt the decision aid was well developed and that it presented the essential information for decision making in an understandable, balanced, and unbiased manner. A majority of respondents (>80%) also felt that the decision aid would guide patients in a logical way, preparing them to participate in decision making and to reach a decision. Fewer physicians (<60%) felt the decision aid would improve the quality of patient visits or be easily implemented into practice and very few (27%) felt that the decision aid would save time. Physicians' intentions to use the decision aid were related to their comfort with offering it to patients, the decision aid topic, and the perceived ease of implementing it into practice. While 54% of the surveyed physicians indicated they would use the decision aid, less than a third followed through with this

    2010-12-01

    The South African HIV and AIDS experience is unique in many ways considering the country's delayed and robust epidemic, the apartheid context, and successive HIV-denialist government regimes. While the struggle for democracy may have overshadowed the enormity of the unfolding HIV epidemic, there was also a delay in constructive religious responses to it early on. In 1990, HIV/AIDS was declared a Catholic institutional focus, and by 2000 the Church had established the largest system of care and treatment in the country besides that of the government. However, the Catholic Church suffered severe criticism on account of its anti-condom policy to HIV prevention. As a result, the institutional Church underwent both organisational and ideological changes in an attempt to adapt to the contextual challenges brought about by HIV and AIDS. Informed by archival collections and oral sources, this article endeavours to critically analyse the HIV/AIDS-related care and treatment activities of the Catholic Church in South Africa between 2000 and 2005. It argues that the complex interplay between HIV and AIDS, the controversy about condom use, and the availability of antiretroviral therapy, accompanied by church activists' multiple engagements with these issues, changed the Church's institutional HIV/AIDS response at that time, in effect transforming the Catholic Church in South Africa into a substantial health asset and agent. However, its stance against the use of condoms for HIV prevention, informed by a larger religious tradition on sexuality, proved to be a health liability.

  17. Event-related potential evidence of accessing gender stereotypes to aid source monitoring.

    Source memory for the speaker's voice (male or female) was investigated when semantic knowledge (gender stereotypes) could and could not inform the episodic source judgment while event-related potentials (ERPs) were recorded. Source accuracy was greater and response times were faster when stereotypes could predict the speaker's voice at test. Recollection supported source judgments in both conditions as indicated by significant parietal "old/new" ERP effects (500-800ms). Prototypical late ERP effects (the right frontal "old/new" effect and the late posterior negativity, LPN) were evident when source judgment was based solely on episodic memory. However, these two late ERP effects were diminished and a novel, frontal-negative ERP with left-central topography was observed when stereotypes aided source judgments. This pattern of ERP activity likely reflects activation of left frontal or left temporal lobes when semantic knowledge, in the form of a gender stereotype, is accessed to inform the episodic source judgment.

  18. Health and environmental effects of complex chemical mixtures: proceedings

    Energy Technology Data Exchange (ETDEWEB)

    1985-01-01

    The Office of Health and Environmental Research (OHER) of the Department of Energy supports a broad long-term research program on human health and environmental effects from potential exposure to energy-related complex chemical mixtures. The program seeks basic mechanistic data on the effects of complex mixtures at the cellular, molecular, and whole animal levels to aid in predicting human health effects and seeks ecological data on biological and physical transformations in the mixtures, concentrations of the mixtures in various compartments of the environment, and potential routes for human exposure to these mixtures (e.g., food chain). On June 17-18, 1985, OHER held its First Annual Technical Meeting on the Complex Chemical Mixtures Program in Chicago, IL. The primary purpose of the meeting was to enable principal investigators to report the research status and accomplishments of ongoing complex chemical mixture studies supported by OHER. To help focus future research directions round table discussions were conducted.

    The recommendations of a staff member of the Paulina Luisi Movement and member of the Women's Global Network for Reproductive Rights were six-fold. Being a woman was considered a risk factor for AIDS. AIDS and HIV infection prevention must concentrate on prevention of sexually transmitted diseases (STDs). 1) Women's organizations have the responsibility for sensitizing health professionals about STDs and AIDS and break the "culture of silence." 2) Women's health focus must actively include prevention of AIDS/HIV. 3) The Pap test must be included routinely as part of public and individual health services and conducted with high quality standards. 4) The flow of communication about women's health issues must be initiated between health professionals and women advocates with the objective of changing concepts and attitudes and of developing complementary strategies. 5) The strategy of promoting condom use and quality information does not address the larger issue of discrimination against women. Gender relations between spouses and between patient and doctor must be based on responsibility, reciprocity, and autonomy. Strategies must aim to combat the negativity in society that prevents responsible gender relations. 6) Professional women who have an awareness of gender issues must be engaged in international and governmental institutions with decision making power. Sex and women's health have been lesser priorities. The health system has responded to women as "objects" rather than subjects of attention. Women's position sexually and socially makes them more vulnerable to AIDS and HIV infections, which may be transmitted through a single sexual contact. STDs increase the risk of AIDS. Latin American women feel shame about STDS, while men respond to STDs as a condition of their sexual virility or potency. Treatment of STDS, much less AIDS prevention, is inadequate. The health system must stop treating women as objects and give them their right to health.

The main outcome measure was the proportion of correct responses to multiple-choice questions relating to four burn scenarios: (1) scald, (2) contact burn, (3) ignited clothing, and (4) chemical burn. A total of 2602 responses were obtained. Large gaps (30-50% incorrect answers) were identified in burn first aid knowledge across all scenarios. 15% more individuals gave correct answers if they had attended a first aid course compared to those who had not (pfirst aid knowledge. Gender and age were significant predictors of first aid course attendance, with males and younger (≤25 years) and older (≥65 years) age-groups less likely to have attended a first aid course. In this sample, first aid training undertaken within the last 5 years with a specific burns component was associated with enhanced burn first aid knowledge. Copyright © 2013 Elsevier Ltd and ISBI.

    Full Text Available Providing foreign aid to developing countries is one of the most important aspects of contemporary foreign politics. The article studies relations between India and Bangladesh from the perspective of foreign aid flows and discovers conditions, forms, mechanisms, and trends of India’s aid to Bangladesh from 1971 until today. The research uses the approach of the Organization for Economic Cooperation and Development (OECD towards foreign aid and understands it as financial assistance, technical assistance, as well as aid in goods in the form of grants and soft loans with the aim to provide economic development and well-being. The author analyzes factors of the geopolitical significance of Bangladesh for India and studies India’s aid to Bangladesh in the context of the history of bilateral relations between the two countries. As a result, a certain correlation is discovered between aid flows and the state of bilateral relations. China’s growing interest is seen as one of additional factors, which cause India to increase volumes of its aid to the neighboring countries, including Bangladesh. China and India are understood as emerging donors who are competing to increase their influence in the world. The two Asian giants have recently taken considerable aid commitments to Bangladesh which indicates that Bangladesh starts to play a more important role in the regional geopolitics. In this context, the article predicts a further growth in the volumes of Indian aid to Bangladesh in the future and concludes that India uses its foreign aid programs as a tool to promote its own economic, political, and strategic interests. Foreign aid, including official development assistance (ODA, is becoming a means of India’s economic diplomacy although some researchers point to the fact that the country’s policymakers still lack coordination to make aid efficient in terms of political gains.

  2. Conceptualizing the cross-cultural gaps in managing international aid: HIV/AIDS and TB project delivery in Southern Africa.

    There appears to be a gap between the billions of dollars inputted into fighting HIV/AIDS and TB and outcomes. This in part can be attributed to the lack of attention in International Development to managing programmes and projects within complex levels of cross-cultural interactions. International Development often ignores management issues, yet Management Studies is left wanting through a lack of engagement with development issues including the fight against disease and poverty. This paper attempts to link these two disciplines towards mutual benefit, through a critical cross-cultural approach. It provides contextualization of international development policies/strategies; conceptualization of dominant paradigms; structural analysis of how a programme/project fits into the global governance structure; analysis of complexities and levels of cross-cultural interaction and their consequences and the process and implications of knowledge transfer across cultural distances. It concludes with implications for policy and practice, as well as what is needed from cross-disciplinary research. This includes how feedback loops can be strengthened from local to global, how indigenous knowledge may be better understood and integrated, how power relations within the global governance structure could be managed, how cross-cultural interaction could be better understood, and how knowledge transfer/sharing should be critically managed.

    AIDS-related stigma is a major contributor to the health and psychosocial well-being of children affected by AIDS. Whilst it is often suggested that AIDS-affected children may be stigmatised by other children, to date no research focuses specifically on child-on-child stigma. Using social representations theory, we explore how Zimbabwean children represent AIDS-affected peers, examining (i) whether or not they stigmatise, (ii) the forms stigma takes, and (iii) the existence of non-stigmatising representations that might serve as resources for stigma-reduction interventions. Our interest in identifying both stigmatising and non-stigmatising representations is informed by a theory of change which accords a central role to community-level debate and dialogue in challenging and reframing stigmatising representations. In late 2008, 50 children (aged 10–12) were asked to “draw a picture of a child whose family has been affected by AIDS in any way”, and to write short stories about their drawings. Thematic analysis of stories and drawings revealed frequent references to stigmatisation of AIDS-affected children – with other children refusing to play with them, generally keeping their distance and bullying them. However children also frequently showed a degree of empathy and respect for AIDS-affected children’s caring roles and for their love and concern for their AIDS-infected parents. We argue that a key strategy for stigma-reduction interventions is to open up social spaces in which group members (in this case children) can identify the diverse and contradictory ways they view a stigmatised out-group, providing opportunities for them to exercise agency in collectively challenging and renegotiating negative representations. Contrary to the common view that drawings enable children to achieve greater emotional expression than written stories, our children’s drawings tended to be comparatively stereotypical and normative. It was in written stories that children

    Full Text Available HIV/AIDS is a global problem with an estimated 40 million infected people. In less than two years, this figure will leap to 100 million according to the World Health Organisation (WHO. By 2005,65 million people will be infected. Half of the number of people in this group will be under 25 years old, and will die before they reach the age of 35. In a South African study done by the Human Science Research Council and published in 2003, regarding the impact of HIV/AIDS on the health sector, the findings were that 15% of health workers in public and private hospitals tested positive for HIV antibodies. Together with these facts above it was found that 46.2 percent of patients served in medical and paediatric wards tested positive for HIV. These factors have major implication for staffing in the future and the role of the nurse manager in South Africa. The aim of the study: to explore the management of HIV/AIDS in the workplace of nurses in selected health services in KwaZulu-Natal. This research was part of a greater study on the exploration of the presence of caring as part of nursing management. . The methodology: the qualitative research approach was used with a phenomenological design, which ensured that the richness and the complexities are reflected in the study. The data was collected by means of an open-ended question to nurse managers during an interview. The first question posed was; How do you or your s e n ’ices care fo r nurses in this hospital? Secondly nurse managers were asked, To explain their role in caring for HIV/AIDS positive nurses on their staff establishment. . The results: a qualitative analysis of the interviews with nurse managers indicated that they rate HIV/AIDS issues as an important part of their management task. Four main themes were identified, namely HIV/AIDS, counselling, dying of AIDS and funerals. Rich descriptions of these themes are given in this paper. Nurse managers in the health services are managing HIV/AIDS

    Food air currently constitutes nearly 15% of official development assistance and hence has considerable potential as a stimulant to growth in less-developed countries (LDCs). This paper reviews the evidence on the impact of food aid on growth and its associated factors. While recognizing that the use of food aid is influenced by a constellation of interests in recipient and donor countries, it identifies a set of guiding principles for maximizing the effectiveness of food aid. These include the need for food (relative to other development needs), its level of substitutability with commercial imports, its incorporation in a poverty-oriented development plan, its guaranteed availability and its complementarity with financial aid. Current food air programs recognize the relevance of some of these principles - e.g. the criteria of necessity - but ignore others - notably the need to situate food aid in a comprehensive plan for improving patterns of income distribution in LDCs. 203 notes, 203 references.

  6. Who's talking? Communication between health providers and HIV-infected adults related to herbal medicine for AIDS treatment in western Uganda.

    Communication between patients and physicians about herbal medicine is valuable, enabling physicians to address issues of potential herb-drug interactions and ensuring appropriate medical care. As seemingly harmless herbal remedies may have detrimental interactions with various HIV antiretroviral drugs, the importance of communication is intensified, but often stifled around the use of herbal medicine in the treatment of HIV/AIDS. In western Uganda, 137 HIV-infected adults attending conventional HIV/AIDS treatment programmes (67 of whom were receiving antiretroviral therapy) shared their experiences and perceptions about traditional herbal medicine and related patient-physician communication issues through interviews and focus group discussions. Although close to 64% of respondents reported using herbal medicine after being diagnosed with HIV, only 16% of these respondents had informed their conventional medical practitioners about using these herbs. Furthermore, only 13% of antiretroviral therapy recipients had inquired about concurrent herb-antiretroviral drug use with their HIV/AIDS treatment providers, largely because they perceived a low acceptance and support for herbal medicine by conventional medical practitioners. Importantly however, almost 68% of HIV-infected adults indicated they would be willing to discuss herbal medicine use if directly asked by a conventional medical practitioner, and the overwhelming majority (91%) said they were amenable to following physician advice about herbal medicine. As such, improved patient-physician communication about herbal medicine is needed, and we recommend that herbal medicine histories be completed when patient histories are taken. Also, HIV/AIDS treatment programmes should be encouraged to develop specific patient-physician communication standards and best practice guidelines to ensure that patients can make informed decisions about herb and pharmaceutical drug co-therapy based on known risks, particularly in the

  9. Aid and good governance: Examining aggregate unintended effects of aid.

    Dijkstra, Geske

    2018-06-01

    Although donors generally aim to improve governance in recipient countries by various means, critics claim that the aggregate effect of large aid flows is the deterioration of governance. Aid is said to weaken domestic accountability, sustain authoritarian regimes, increase political instability, weaken government capacities, and increase corruption. Conducting a systematic search in Web of Science, this paper reviews the empirical evidence for these unintended aggregate effects of aid on the political, administrative, and judicial dimensions of good governance. It finds that the negative effects of aid on governance are much exaggerated. The aggregate effect of aid on democracy has become more positive after the Cold War, and the effect of aid on government capacity and on reducing corruption has also improved over time. Furthermore, most studies show a positive effect of aid on political stability. These findings imply that donor intentions matter: donors that are serious about their intended effects on governance are able to mitigate the possible negative unintended effects of their aid.

  15. Gender and HIV/AIDS: Exploring Men and Vulnerability Towards Effective HIV/AIDS Policy Interventions and Sub-Saharan Africa

    2012-06-01

    Full Text Available This article examines the dynamics between HIV/Aids gender policy strategies and the socio-political demands on HIV/Aids interventions in sub-Saharan Africa. Gender in HIV/Aids intervention seems inescapable. Nowhere else is this more marked than in the social dimensions of HIV/Aids prevention in sub-Saharan Africa. This has resulted in prevention strategies, which are encumbered by the reality of poverty, gender, access, power and the various debates on behavioural change. The social constructions of gender roles and power relations play a significant role in the region’s HIV /Aids dynamic. To this end, the mainstreaming of gender issues into national political, social and economic agenda and policies has been championed by international development and economic institutions. In developing HIV/Aids intervention policies, gender has also been mainstreamed, especially where epidemiological data show the disparity in infection rates between men and women, where women are seen as more susceptible to infection. The gendered approach to HIV/Aids appears to typecast women as the vulnerable and suffering face of HIV/Aids, while men, as ‘the other’, are generally regarded as the perpetuators and spreaders of the virus. While there is no doubt that women’s vulnerability in this milieu has been proven within known research evidence to exist, the neglect of institutional (social, cultural and economic and historical vulnerabilities of African men’s realities are sometimes overlooked. Recently, greater focus has shifted to curbing infection rates in men based on new scientific evidence that shows that risk of transmission in circumcised men is reduced. The article argues that such movement towards showing areas of men’s vulnerability as a focus in HIV/Aids policy interventions may have the potential to shift the observed burden that current HIV/Aids policy thrusts inadvertently place on African women. The article will put forward an argument for

    2012-01-01

    We study the problem of existence of geometric structures on compact complex surfaces that are related to split quaternions. These structures, called para-hypercomplex, para-hyperhermitian and para-hyperkähler, are analogs of the hypercomplex, hyperhermitian and hyperkähler structures in the definite case. We show that a compact 4-manifold carries a para-hyperkähler structure iff it has a metric of split signature together with two parallel, null, orthogonal, pointwise linearly independent vector fields. Every compact complex surface admitting a para-hyperhermitian structure has vanishing first Chern class and we show that, unlike the definite case, many of these surfaces carry infinite-dimensional families of such structures. We provide also compact examples of complex surfaces with para-hyperhermitian structures which are not locally conformally para-hyperkähler. Finally, we discuss the problem of non-existence of para-hyperhermitian structures on Inoue surfaces of type S 0 and provide a list of compact complex surfaces which could carry para-hypercomplex structures.

    ABSTRACT OBJECTIVE To analyze the genesis of the policy for controlling AIDS in Brazil. METHODS Socio-historical study (1981-1989), based on Bordieu’s genetic sociology, by document analysis, bibliographical review, and in-depth interviews. It consisted of a connection between the analysis of the paths of 33 agents involved in the creation of a social space focusing on AIDS-related issues and the historical possibility conditions of the drafting of a specific policy. RESULTS AIDS Space is a gathering point for the paths of agents from several social fields (medical, scientific, political, and bureaucratic fields). A specific space for relationships, which enabled the drafting of a policy for controlling the AIDS epidemic, but also a place where the authority to talk about the meaning of the disease, the methods to prevent and treat it was under dispute. The analysis showed how the various structures (democratic administrations in Sao Paulo and at the national level, with public health officers taking important positions) and the lack of a specific therapy contributed to social agents of different ranks and backgrounds to initially set prevention as a priority. CONCLUSIONS The rise of the sanitary movement, the organization of SUS, and the dominance of the medical field at the AIDS Space contributed to foster treatment as a part of the measures to control the epidemic. These conditions allowed drafting a policy based on the integrality of care, by linking prevention and treatment in the following decade, with important participation from state bureaucracy and researchers.

    2011-01-01

    Viet Nam is one of the brightest stars in the constellation of developing countries. Its remarkable achievements in reducing poverty and improving health and education outcomes are well known, and as a result it has enjoyed generous aid programmes. Viet Nam also has a reputation for taking a strong lead in disciplining its donors and pushing for more efficient and effective forms of aid delivery, both at home and internationally. This article discusses how efforts to improve the effectiveness of aid intersect with policy-making processes in the health sector. It presents a quantitative review of health aid flows in Viet Nam and a qualitative analysis of the aid environment using event analysis, participant observation and key informant interviews. The analysis reveals a complex and dynamic web of incentives influencing the implementation of the aid effectiveness agenda in the health sector. There are contradictory forces within the Ministry of Health, within government as a whole, within the donor community and between donors and government. Analytical frameworks drawn from the study of policy networks and governance can help explain these tensions. They suggest that governance of health aid in Viet Nam is characterised by multiple, overlapping 'policy networks' which cut across the traditional donor-government divide. The principles of aid effectiveness make sense for some of these communities, but for others they are irrational and may lead to a loss of influence and resources. However, sustained engagement combined with the building of strategic coalitions can overcome individual and institutional incentives. This article suggests that aid reform efforts should be understood not as a technocratic agenda but as a political process with all the associated tensions, perverse incentives and challenges. Partners thus need to recognise - and find new ways of making sense of - the complexity of forces affecting aid delivery.

  3. The poverty-HIV/AIDS nexus in Africa: a livelihood approach.

    Science.gov (United States)

    Masanjala, Winford

    2007-03-01

    This paper reviews the nexus between poverty and HIV/AIDS in Africa using a sustainable livelihood framework. Much of the literature on HIV and AIDS has generated an almost universal consensus that the AIDS epidemic is having an immense impact on the economies of hard-hit countries, hurting not only individuals, families and firms, but also significantly slowing economic growth and worsening poverty. International evidence has concentrated on the pathways through which HIV/AIDS undermines livelihoods and raises vulnerability to future collapse of livelihoods. Yet, little attention has been paid to the role that social relations and livelihood strategies can play in bringing about risky social interaction that raises the chance of contracting HIV. Using the sustainable livelihood and social relation approaches, this article demonstrates that although AIDS is not simply a disease of the poor, determinants of the epidemic go far beyond individual volition and that some dimensions of being poor increase risk and vulnerability to HIV.

    Despite advances made in recent years in medical first aid, psychiatric intervention, survival training and equipment design, many people still perish quickly during and immediately following a disastrous event. In this study, individuals and groups of survivors of life-threatening events were debriefed and the behavior of those who coped well during such a threat to life were compared with those who did not. The behaviors of those who coped well were distilled into a set of principles for psychological first aid; that is, a series of simple actions for use within a disaster which serves to recover victims to functional behavior as quickly as possible, thus increasing their chance for survival. These principles of psychological first aid have recently been introduced into basic first aid and survival training courses for both military and civilian units.

  7. Exploring Ivorian perspectives on the effectiveness of the current Ivorian science curriculum in addressing issues related to HIV/AIDS

    Ado, Gustave Firmin

    School-based HIV/AIDS science education has the potential to impact students when integrated into the science curriculum. However, this mixed method study shows that school-based HIV/AIDS science education is often not infused into career subjects such as science education but integrated into civics education and taught by teachers who lack the skills, knowledge, and the training in the delivery of effective school HIV/AIDS education. Since science is where biological events take place, it is suggested that HIV/AIDS science merits being taught in the science education classroom. This study took place in nine public middle schools within two school districts in Abidjan, Ivory Coast, one major urban city in the southern region. The study utilized triangulation of multiple data sources---both qualitative and quantitative. To substantiate the claims made in this study, a range of qualitative methods such as field notes and individual interviews with 39 teachers, 63 sixth grade students, 8 school administrators, and 20 community elders were used. For the quantitative portion 140 teachers and 3510 sixth grade students were surveyed. The findings from the study prioritize science education that includes HIV/AIDS science education for all, with emphasis on HIV/AIDS prevention in Ivory Coast. The factors that influence the implementation of HIV/AIDS curricula within the Ivorian sixth grade classrooms are discussed. Interview and survey data from students, teachers, school administrators, and community elders indicate that in the Ivorian school setting, "gerontocratic" cultural influences, religious beliefs, personal cultural beliefs, and time spent toward the discourse on HIV/AIDS have led to HIV/AIDS education that is often insufficient to change either misconceptions about HIV/AIDS or risky practices. It was also found that approaches to teaching HIV/AIDS does not connect with youth cultures. By reframing and integrating current HIV/AIDS curricula into the science

    Full Text Available This paper introduces a novel soft computing technique, called the complex neutrosophic soft expert relation (CNSER, to evaluate the degree of interaction between two hybrid models called complex neutrosophic soft expert sets (CNSESs. CNSESs are used to represent two-dimensional data that are imprecise, uncertain, incomplete and indeterminate. Moreover, it has a mechanism to incorporate the parameter set and the opinions of all experts in one model, thus making it highly suitable for use in decision-making problems where the time factor plays a key role in determining the final decision. The complex neutrosophic soft expert set and complex neutrosophic soft expert relation are both defined. Utilizing the properties of CNSER introduced, an empirical study is conducted on the relationship between the variability of the currency exchange rate and Malaysian exports and the time frame (phase of the interaction between these two variables. This study is supported further by an algorithm to determine the type and the degree of this relationship. A comparison between different existing relations and CNSER to show the ascendancy of our proposed CNSER is provided. Then, the notion of the inverse, complement and composition of CNSERs along with some related theorems and properties are introduced. Finally, we define the symmetry, transitivity and reflexivity of CNSERs, as well as the equivalence relation and equivalence classes on CNSESs. Some interesting properties are also obtained.

    This article assesses the association of women's HIV/AIDS knowledge of transmission and prevention with socioeconomic status (SES). Data from the 2004 Lebanese PAPFAM (Pan-Arab Project for Family Health) survey were used. The survey was based on a representative household sample (n = 5532 households; n = 3315 women) of ever-married women aged 15 to 55 years. Adjusted analysis revolved around multivariate logistic regression models. 18% of women were knowledgeable of HIV/AIDS transmission methods and 21% of prevention methods. Income and education were significantly related to women's transmission and prevention knowledge. Significant differences were also found by region and media exposure. Women in the richest income quintile were 4 times (95% confidence interval [CI] = 2.43-6.42) more likely to be knowledgeable than those in the poorest. Women with the highest education were 2.57 times more likely (95% CI = 1.98-3.34) to be knowledgeable than those with elementary education or less. These results suggest the need for incorporating contextual regional and population differences for more effective HIV/AIDS awareness campaigns in Lebanon. © 2011 APJPH.

  10. Analytical evaluation of computer-based decision aids

    International Nuclear Information System (INIS)

    Kisner, R.A.

    1985-01-01

    This paper introduces a method for evaluating decision aids for nuclear power plant operators. The method involves a two-stage process of classification and analytical evaluation of display form and content. The classification scheme relates each specific aid to one or more general decision-making tasks. Evaluation then proceeds using a normative top-down design process based on the classification scheme by determining or deducing how various design issues associated with this process were resolved by the designer. The result is an assessment of the ''understandability'' of the aid as well as identification of the training and display features necessary to ensure understandability. 7 refs., 4 figs., 1 tab

    First-year students at a midwestern medical school are introduced to a comprehensive approach to the biological, psychological, and social aspects of acquired immune deficiency syndrome (AIDS). In a seven-week elective seminar (approximately 12 hours in length), the students view a television movie and a documentary film about persons with AIDS and their families and friends, and they participate in roundtable discussions with AIDS patients, volunteers who coordinate support and advocacy for persons with AIDS, and health care professionals involved in the care of AIDS patients. They receive reading materials and lectures on the pathology, epidemiology, and history of AIDS, and they monitor and discuss radio and television reporting on AIDS. In wrap-up sessions and evaluation questionnaires, the students have reported the seminar to be valuable in helping them overcome their fear of the disease, develop empathy for patients with catastrophic diseases, and understand a comprehensive approach to a complex disease.

    Costs are an important component of patients' decision making, but a comparatively underemphasized aspect of formal shared decision making. We hypothesized that decision aids also avoid discussion of costs, despite their being tools designed to facilitate shared decision making about patient-centered outcomes. We sought to define the frequency of cost-related information and identify the common modes of presenting cost and cost-related information in the 290 decision aids catalogued in the Ottawa Hospital Research Institute's Decision Aid Library Inventory (DALI) system. We found that 56% (n = 161) of the decision aids mentioned cost in some way, but only 13% (n = 37) gave a specific price or range of prices. We identified 9 different ways in which cost was mentioned. The most common approach was as a "pro" of one of the treatment options (e.g., "you avoid the cost of medication"). Of the 37 decision aids that gave specific prices or ranges of prices for treatment options, only 2 were about surgery decisions despite the fact that surgery decision aids were the most common. Our findings suggest that presentation of cost information in decision aids is highly variable. Evidence-based guidelines should be developed by the International Patient Decision Aid Standards (IPDAS) Collaboration. © The Author(s) 2015.

    augmentation of heterosexual transmission and IDUs as transmission groups, are described and analised. The geographical distribution of the AIDS cases registered between 1987-1993 in Brazil throughout the Brazilian States is evaluated by means of worksheets, maps, and non-parametric statistics. Results show that Gravimetric Centers (obtained by the use of the calculus spatial means of AIDS in Brazil are situated within a triangle the sides of which are formed lines joining the three main metropolitan areas of the wealthiest region of Brazil - the southeast, i.e. São Paulo, Rio de Janeiro and Belo Horizonte. These especially S. Paulo, function as points of attraction for these Gravimetric Centers (GCs towards the south as compared with the GCs of the general population calculated ia accordance with data from the 1980 and 1991 censuses. It is possible to observe a displacement of the GCs toward the northwest over this period in accordance with the migration patterns of the Brazilian population in general, though with a dynamic of its own. These changes in the geographical, socio-demographic and transmission group patterns show the complex nature of the epidemic in Brazil and pose additional difficulties for the development of prevention strategies.

  14. Light harvesting complexes of Chromera velia, photosynthetic relative of apicomplexan parasites

    2013-06-01

    The structure and composition of the light harvesting complexes from the unicellular alga Chromera velia were studied by means of optical spectroscopy, biochemical and electron microscopy methods. Two different types of antennae systems were identified. One exhibited a molecular weight (18-19 kDa) similar to FCP (fucoxanthin chlorophyll protein) complexes from diatoms, however, single particle analysis and circular dichroism spectroscopy indicated similarity of this structure to the recently characterized XLH antenna of xanthophytes. In light of these data we denote this antenna complex CLH, for "Chromera Light Harvesting" complex. The other system was identified as the photosystem I with bound Light Harvesting Complexes (PSI-LHCr) related to the red algae LHCI antennae. The result of this study is the finding that C. velia, when grown in natural light conditions, possesses light harvesting antennae typically found in two different, evolutionary distant, groups of photosynthetic organisms. © 2013 Elsevier B.V.

    Activation-induced cytidine deaminase (AID) is the mutator enzyme in adaptive immunity. AID initiates the antibody diversification processes in activated B cells by deaminating cytosine to uracil in immunoglobulin genes. To some extent other genes are also targeted, which may lead to genome instability and B cell malignancy. Thus, it is crucial to understand its targeting and regulation mechanisms. AID is regulated at several levels including subcellular compartmentalization. However, the complex nuclear distribution and trafficking of AID has not been studied in detail previously. In this work, we examined the subnuclear localization of AID and its interaction partner CTNNBL1 and found that they associate with spliceosome-associated structures including Cajal bodies and nuclear speckles. Moreover, protein kinase A (PKA), which activates AID by phosphorylation at Ser38, is present together with AID in nuclear speckles. Importantly, we demonstrate that AID physically associates with the major spliceosome subunits (small nuclear ribonucleoproteins, snRNPs), as well as other essential splicing components, in addition to the transcription machinery. Based on our findings and the literature, we suggest a transcription-coupled splicing-associated model for AID targeting and activation. - Highlights: • AID and its interaction partner CTNNBL1 localize to Cajal bodies and nuclear speckles. • AID associates with its activating kinase PKA in nuclear speckles. • AID is linked to the splicing machinery in switching B-cells. • Our findings suggest a transcription-coupled splicing associated mechanism for AID targeting and activation.

  16. Risk analysis. HIV / AIDS country profile: Senegal.

    Science.gov (United States)

    1996-12-01

    Since the first acquired immunodeficiency syndrome (AIDS) case was confirmed in 1986, Senegal has conducted an aggressive prevention campaign. Senegal's National AIDS Committee has noted the contributions of poverty and migration to the spread of AIDS. By June 1994, 1297 AIDS cases had been reported and an estimated 500,000 people (1.4% of the population) were infected with human immunodeficiency virus (HIV)-1 and 2. The highest rate of HIV infection (14%) exists among commercial sex workers. At present, HIV/AIDS cases are concentrated in Dakar, Kaolack, the Matam region, and Ziguinchor; however, the growing importance of inter-regional trading is expected to spread HIV to the smaller towns and rural areas. Also salient is the recent devaluation by 50% of the CFA franc, which has reduced the public sector workforce and led many poor urban residents into commercial sex work. CFA devaluation has made Senegal attractive to tourists and business visitors--another factor responsible for growth of the legalized commercial sex industry. Although sex workers are instructed in condom use and tested annually for HIV, only 850 of the 2000 registered sex workers have reported for check-ups, and the majority of prostitutes are unregistered. Senegal's AIDS Plan for 1994-98 focuses on care of AIDS patients, pressures placed on family structures by HIV, and AIDS-related erosions in the status of women. Each health service region has its own local plan for AIDS/HIV and sexually transmitted diseases, supervised by a regional committee. Public education has involved outreach to religious leaders, promotion of affordable condoms, and distribution of over 75,000 leaflets to key target populations. About US $16 million of the $25,688,875-budget HIV/AIDS program for 1994-98 was pledged by external donors.

    Renata Aparecida Leite

    Full Text Available Abstract Introduction The electrophysiological responses obtained with the complex auditory brainstem response (cABR provide objective measures of subcortical processing of speech and other complex stimuli. The cABR has also been used to verify the plasticity in the auditory pathway in the subcortical regions. Objective To compare the results of cABR obtained in children using hearing aids before and after 9 months of adaptation, as well as to compare the results of these children with those obtained in children with normal hearing. Methods Fourteen children with normal hearing (Control Group - CG and 18 children with mild to moderate bilateral sensorineural hearing loss (Study Group - SG, aged 7-12 years, were evaluated. The children were submitted to pure tone and vocal audiometry, acoustic immittance measurements and ABR with speech stimulus, being submitted to the evaluations at three different moments: initial evaluation (M0, 3 months after the initial evaluation (M3 and 9 months after the evaluation (M9; at M0, the children assessed in the study group did not use hearing aids yet. Results When comparing the CG and the SG, it was observed that the SG had a lower median for the V-A amplitude at M0 and M3, lower median for the latency of the component V at M9 and a higher median for the latency of component O at M3 and M9. A reduction in the latency of component A at M9 was observed in the SG. Conclusion Children with mild to moderate hearing loss showed speech stimulus processing deficits and the main impairment is related to the decoding of the transient portion of this stimulus spectrum. It was demonstrated that the use of hearing aids promoted neuronal plasticity of the Central Auditory Nervous System after an extended time of sensory stimulation.

  18. Differential programming of B cells in AID deficient mice.

    Directory of Open Access Journals (Sweden)

    Marc A Hogenbirk

    Full Text Available The Aicda locus encodes the activation induced cytidine deaminase (AID and is highly expressed in germinal center (GC B cells to initiate somatic hypermutation (SHM and class switch recombination (CSR of immunoglobulin (Ig genes. Besides these Ig specific activities in B cells, AID has been implicated in active DNA demethylation in non-B cell systems. We here determined a potential role of AID as an epigenetic eraser and transcriptional regulator in B cells. RNA-Seq on different B cell subsets revealed that Aicda(-/- B cells are developmentally affected. However as shown by RNA-Seq, MethylCap-Seq, and SNP analysis these transcriptome alterations may not relate to AID, but alternatively to a CBA mouse strain derived region around the targeted Aicda locus. These unexpected confounding parameters provide alternative, AID-independent interpretations on genotype-phenotype correlations previously reported in numerous studies on AID using the Aicda(-/- mouse strain.

    2010-04-28

    Many conventional technologies for fabricating tissue engineering scaffolds are not suitable for fabricating scaffolds with patient-specific attributes. For example, many conventional technologies for fabricating tissue engineering scaffolds do not provide control over overall scaffold geometry or over cell position within the scaffold. In this study, the use of computer-aided laser micromachining to create scaffolds for vascular tissue networks was investigated. Computer-aided laser micromachining was used to construct patterned surfaces in agarose or in silicon, which were used for differential adherence and growth of cells into vascular tissue networks. Concentric three-ring structures were fabricated on agarose hydrogel substrates, in which the inner ring contained human aortic endothelial cells, the middle ring contained HA587 human elastin and the outer ring contained human aortic vascular smooth muscle cells. Basement membrane matrix containing vascular endothelial growth factor and heparin was to promote proliferation of human aortic endothelial cells within the vascular tissue networks. Computer-aided laser micromachining provides a unique approach to fabricate small-diameter blood vessels for bypass surgery as well as other artificial tissues with complex geometries.

    Besides Mycobacterium tuberculosis, a number of other Mycobacterium species are also occasional human pathogens. Tuberculosis due to Mycobacterium avium complex (MAC) and Mycobacterium kansasii is particularly prevalent in AIDS patients as compared to the normal population. A cross-sectional study was carried out during January 2004 to August 2005 in 100 HIV-infected persons visiting Tribhuvan University, Teaching Hospital, and about a dozen of HIV/AIDS care centers of Kathmandu with the objectives to characterize the different mycobacterial species in HIV/AIDS patients. Three sputum specimens from each person were used to investigate tuberculosis by Ziehl-Neelsen staining, culture and identification tests. Among the 100 HIV-infected cases, 66 (66%) were males and 34 (34%) were females. Sixty percent of the cases were in the age group of 21-30 years. Mycobacteria were detected in 23 (23%) HIV cases of which 15 (65.2%) were in the age group of 21-30 years ; 17(74%) were males and 6 (26 %) were females. Among 23 co-infected cases, 22 were culture positive for mycobacteria. Among these, the predominant one was Mycobacterium avium complex (MAC), 9 (41%), followed by M. tuberculosis, 6 (27%), M .kansasii, 4 (18%), M. fortuitum, 2 (10%) and M. chelonae 1 (4%). Significant relationship was established between smoking/alcoholism and the subsequent development of tuberculosis (chi(2)=7.24, p<0.05 for smoking habit and chi(2)=4.39, p<0.05 for alcoholism). Fourteen (61%) co-infected cases presented with weight loss and cough whereas diarrhea was presented only by those patients with atypical mycobacterial co-infection, which was as high as 5 (56%) in patients with MAC co-infection. This study demonstrated the predominance of atypical mycobacteria, mainly MAC, in HIV/AIDS cases and most of them were from sputum smear-negative cases.

    2011-12-01

    To review recent advance in the research and application of computer aided forming techniques for constructing bone tissue engineering scaffolds. The literature concerning computer aided forming techniques for constructing bone tissue engineering scaffolds in recent years was reviewed extensively and summarized. Several studies over last decade have focused on computer aided forming techniques for bone scaffold construction using various scaffold materials, which is based on computer aided design (CAD) and bone scaffold rapid prototyping (RP). CAD include medical CAD, STL, and reverse design. Reverse design can fully simulate normal bone tissue and could be very useful for the CAD. RP techniques include fused deposition modeling, three dimensional printing, selected laser sintering, three dimensional bioplotting, and low-temperature deposition manufacturing. These techniques provide a new way to construct bone tissue engineering scaffolds with complex internal structures. With rapid development of molding and forming techniques, computer aided forming techniques are expected to provide ideal bone tissue engineering scaffolds.

    Human immunodeficiency virus infection is a global crisis that represents a serious health threat, particularly among younger people. Various studies show that both orphan and non-orphan adolescents and youths experience vulnerability to HIV. Nevertheless, the findings hitherto are mixed and inconclusive. The aim of this study, therefore, was to assess the prevalence of parental death and its association with multiple sexual partners among secondary school students for evidence based interventions. A cross-sectional study was conducted among secondary school youth in Addis Ababa, Ethiopia. A multistage sampling technique was used to select a representative sample of 2,169 school youths. Sexual health behavior related data were collected using self-administered questionnaire. Binary logistic regression was employed to examine the relation between parental death and multiple sexual partners. Among the 2,169 eligible study participants 1948 (90%) completed the self-administered questionnaires. Of those 1,182(60.7%) were females. The overall prevalence of parental death was 347(17.8%.) with 95% CI (16.2%, 19.6%). The HIV/AIDS proportionate mortality ratio was 28% (97/347).A multivariate logistic regression analysis showed that high HIV/AIDS related knowledge (AOR = 0.39; 95% CI, 0.18-0.84), positive attitude towards HIV prevention methods (AOR = 0.48; 95% CI, 0.23-0.97), being tested for HIV (AOR = 0.52; 95% CI, 0.31-0.87) and chewing Khat (AOR = 2.59; 95% CI,1.28-5.26)] were significantly associated with having multiple sexual partners among secondary school youths. Significant proportion of secondary school youths had lost at least one parent due to various causes. High knowledge of HIV/AIDS, positive attitude towards 'ABC' rules for HIV prevention, being tested for HIV and chewing khat are more likely to be factors associated with multiple sexual partnership among secondary school students in Addis Ababa.Therefore, the school based interventions

    2013-01-01

    As early as the 1930s the term Master Hearing Aid (MHA) described a device used in the fitting of hearing aids. In their original form, the MHA was a desktop system that allowed for simulated or actual adjustment of hearing aid components that resulted in a changed hearing aid response. Over the years the MHA saw many embodiments and contributed to a number of rationales for the fitting of hearing aids. During these same years, the MHA was viewed by many as an inappropriate means of demonstrating hearing aids; the audio quality of the desktop systems was often superior to the hearing aids themselves. These opinions and the evolution of the MHA have molded the modern perception of hearing aids and the techniques used in the fitting of hearing aids. This article reports on a history of the MHA and its influence on the fitting of hearing aids. PMID:23686682

  8. An Ontology for Modeling Complex Inter-relational Organizations

    Science.gov (United States)

    Wautelet, Yves; Neysen, Nicolas; Kolp, Manuel

    This paper presents an ontology for organizational modeling through multiple complementary aspects. The primary goal of the ontology is to dispose of an adequate set of related concepts for studying complex organizations involved in a lot of relationships at the same time. In this paper, we define complex organizations as networked organizations involved in a market eco-system that are playing several roles simultaneously. In such a context, traditional approaches focus on the macro analytic level of transactions; this is supplemented here with a micro analytic study of the actors' rationale. At first, the paper overviews enterprise ontologies literature to position our proposal and exposes its contributions and limitations. The ontology is then brought to an advanced level of formalization: a meta-model in the form of a UML class diagram allows to overview the ontology concepts and their relationships which are formally defined. Finally, the paper presents the case study on which the ontology has been validated.

  13. Complexity Triggered by Economic Globalisation— The Issue of On-Line Betting-Related Match Fixing

    Directory of Open Access Journals (Sweden)

    Wladimir Andreff

    2017-02-01

    Full Text Available Complexity in mainstream economics consists in high intermediary consumption of mathematics. A new approach to complexity economics dwells upon path-dependent global systems; their emergence and evolving organisation. The focus here is on the complexity of the real economic world due to globalisation. On-line betting related match-fixing is a case in point about which the article presents non-exhaustive empirical evidence and shows how it is analysed with the standard model of the economics of crime. There is no room for complexity in such an individualistic approach to corrupt behaviour applied to bet-related fixes. A more complex model is sketched based on interactions between a global (though underground market for fixes and the actual partly legal, partly illegal global sport betting market. These interactions exhibit how complex is the issue of combating betting-related match fixing. Reviewing those major policies envisaged for containing the latter—prohibition; sanctions; regulation; privatisation (betting rights—the article opts for a global ‘Sportbettobin’ tax on sport betting gains; in the same vein as the famous Tobin tax on international capital transfers. The novelty in this approach is a variable (increasing rate applied to increasing tranches of taxation (gains which should dry up the worst cases of on-line bettingrelated match fixing.

  14. AIDS: A theological and pastoral response

    Directory of Open Access Journals (Sweden)

    G. G. Miller

    1990-03-01

    Full Text Available The anticipated A.I.D.S. crisis in Southern Africa presents an opportunity for the Christian church to respond positively rather than merely to react negatively. This requires both a theological understanding and a pastoral response. Theologically, A.I.D.S. may be seen as an object lesson in the interrelation of natural, personal and historical evil. Although both the Old Testament and the New Testament warn against a simplistic doctrine of individual retribution, there are also several different ways in which the A.I.D.S. crisis may indeed in some particular cases be seen as a judgement of God while in other cases it is rather a horrifying event. Other relevant issues include matters relating to justification and sanctification and the wider ethical issues of discrimination and human rights, of "public" and "private" morality. The Church's pastoral response should include both "corrective" education to remove irrational and fearful ignorance and also "preventative" education to encourage a monogamous lifestyle. Pastoral ministry must be "redemptive", appropriate to the varying needs of persons with A.I.D.S., of their families and friends and of professional care-providers. The Church cannot ignore the A.I.D.S. crisis, but must respond to it both Biblically and pastorally.

  16. The complex and quaternionic quantum bit from relativity of simultaneity on an interferometer.

    Garner, Andrew J P; Müller, Markus P; Dahlsten, Oscar C O

    2017-12-01

    The patterns of fringes produced by an interferometer have long been important testbeds for our best contemporary theories of physics. Historically, interference has been used to contrast quantum mechanics with classical physics, but recently experiments have been performed that test quantum theory against even more exotic alternatives. A physically motivated family of theories are those where the state space of a two-level system is given by a sphere of arbitrary dimension. This includes classical bits, and real, complex and quaternionic quantum theory. In this paper, we consider relativity of simultaneity (i.e. that observers may disagree about the order of events at different locations) as applied to a two-armed interferometer, and show that this forbids most interference phenomena more complicated than those of complex quantum theory. If interference must depend on some relational property of the setting (such as path difference), then relativity of simultaneity will limit state spaces to standard complex quantum theory, or a subspace thereof. If this relational assumption is relaxed, we find one additional theory compatible with relativity of simultaneity: quaternionic quantum theory. Our results have consequences for current laboratory interference experiments: they have to be designed carefully to avoid rendering beyond-quantum effects invisible by relativity of simultaneity.

  17. [First-aid in France. Current situation and future perspectives].

    First-aid--treatment aimed at enabling a victim to survive pending the arrival of qualified medical support--is less well developed in France than in many other industrialized countries, especially among the general public. The current status of first-aid in France is paradoxical: schooling is free and obligatory, the ambulance service and emergency services are of the highest quality, but the general public are too often passive and unknowledgeable when faced with an emergency situation. This situation is due to several factors, including the complexity of first-aid training and regulations, the involvement of too many public bodies, the legal liability of the first-aider, and a lack of ongoing training. The French National Academy of Medicine recommends 8 measures to improve this situation: Provide a legal definition of first-aid: "a set of recognized measures aimed, in an emergency setting, at preserving the physical and psychological integrity of the victim of an accident or illness, notably pending the arrival of professional medical assistance". Waive, as in many other countries, civil and legal responsibility for the non professional first-aider, except in case of clear negligence. Reinforce the organization of first-aid in France in order to monitor the number and quality of first-aiders, and to ensure theoretical and pedagogic research; create a communications department capable of supporting and promoting first-aid. Improve access to first-aid training by increasing the number of situations in which it is obligatory (driving tuition, school and university examinations, group responsibility, at-risk practices), by providing financial assistance for certain groups, and by ensuring routine training at school, in the armed forces, and in the workplace. Create a progressive and integrated citizen first-aid training course with individual modules, ensuring that first-aiders update and perfect their knowledge throughout life.

    2011-01-01

    AIDS has become the new plague; a disease that is not only physically and psychologically debilitating, but culturally and socially devastating as well. Like the plague, AIDS has caused fear, prejudice and even panic in society. Although there are remarkable improvements in the diagnosis and treatment of the disease, AIDS continues its grim passage around the globe. After a slight downturn in the early 1990's, it then returned with a vengeance. By the end of the 20(th) century, AIDS was reliably estimated to have caused over 20 million deaths throughout the world. At the same time, 40 million people were estimated to be HIV positive. This paper provides an overview of the history of AIDS, including the discovery and its progress in the world through philately. Philately is the study of stamps and postal history and other related items. Philately involves more than just stamp collecting, it contains the study of the design and educational impact of a philatelic material. We have presented AIDS stamps produced world-wide to emphasize the history of AIDS.

    Several laboratory studies have demonstrated that working memory may influence response to compression speed in controlled (i.e., laboratory) comparisons of compression. In this study, the authors explored whether the same relationship would occur under less controlled conditions, as might occur in a typical audiology clinic. Participants included 27 older adults who sought hearing care in a private practice audiology clinic. Working memory was measured for each participant using a reading span test. The authors examined the relationship between working memory and aided speech recognition in noise, using clinically fit hearing aids with a range of compression speeds. Working memory, amount of hearing loss, and age each contributed to speech recognition, but the contribution depended on the speed of the compression processor. For fast-acting compression, the best performance was obtained by patients with high working memory. For slow-acting compression, speech recognition was affected by age and amount of hearing loss but was not affected by working memory. Despite the expectation of greater variability from differences in compression implementation, number of compression channels, or attendant signal processing, the relationship between working memory and compression speed showed a similar pattern as results from more controlled, laboratory-based studies.

    A fiber optic aided spectrophotometric technique has been developed for the determination of free acidity in nuclear fuel reprocessing streams. In this method, nitric acid forms yellow colour complex with chrome azurol s. The system obeys Lambert-Beer's law at 542 nm in the range of acidity 4-14 M. The molar absorption coefficient (ε) and Sandell's sensitivity (S) of complex are 5.23 × 10 3 L.mol -1 .cm -1 and 1.91 × 10 -4 µg/cm 2 respectively. Relative standard deviation is less than 1 % and correlation coefficient is 0.999. Results of the present method are in good agreement with those obtained by the standard procedure. (author)

    Despite the mistaken belief in Central America that AIDS is primarily a disease of male homosexuals, some 21% of reported cases in Guatemala have been women 15-44 years old. Many Guatemalan women are at risk of AIDS and other sexually transmitted diseases (STDs) because of their lack of sexual bargaining power and negotiating skills, the widespread acceptance of male infidelity in marriage, tolerance of bisexual relations and frequenting of prostitutes, and ignorance of women about sexuality. Condom use is infrequent in Guatemala. Most men and women lack knowledge of AIDS and other STDs and have no perception of their own vulnerability. Male alcohol use and violence against women diminishes the ability of women to protect themselves. Sex education and information about STDs should be provided for both men and women to slow the spread of AIDS. AIDS educators should direct their messages to women toward promoting condom use, increasing knowledge of AIDS and STDs, providing basic sex education, questioning stereotypes of AIDS patients as persons with disordered lifestyles, encouraging realistic assessment of risks, and assisting women to increase their negotiating ability in sexual relations. Three crucial ways of helping women protect themselves are by making them aware of the influence of gender roles in their reproductive lives, teaching them communication and negotiating skills, and providing strategies for them to confront alcohol abuse and gender violence. Survey results indicate that Guatemalan women were extremely motivated to protect their children and secondarily to maintain their homes and be good wives. Motivational messages for AIDS prevention should be related to children and the family. Men were found to be concerned about their families as well and to fear the stigma of HIV infection. Educational techniques for AIDS prevention should be accessible to the illiterate and should focus on life stories or similar methods that make AIDS seem less abstract to

    Six AIDS patients with Pneumocystis carinii pneumonia (PCP) underwent {sup 67}Ga scan as part of their evaluation. Only one patient of them showed the characteristic {sup 67}Ga distribution pattern for PCP, that is, diffuse, increased, bilateral lung activity greater than liver activity. Two patients who were receiving therapy for PCP and one patient with recurrent PCP showed focal or uneven {sup 67}Ga lung uptake. In the four patients, the scan showed more extensive lesion than the chest radiograph. The other two patients who died 2 months later of cellular immunodeficiency showed no or very slight lung uptake of {sup 67}Ga. In summary, {sup 67}Ga scanning is useful diagnostic procedure in evaluation of PCP in patients with AIDS. (author).

  7. Gauging Change in Australian Aid: Stakeholder Perceptions of the Government Aid Program.

    Wood, Terence; Burkot, Camilla; Howes, Stephen

    2017-05-01

    In this article, we use data from the 2013 and 2015 Australian Aid Stakeholder Surveys to gauge the extent of the changes to the Australian Government Aid Program since the 2013 federal election. The two surveys targeted the same set of stakeholders of the aid program, and both gathered data on a wide range of aspects of its functioning. As we assess the findings that emerged from the surveys, we situate our work amongst recent academic studies that have looked at the post-2013 aid changes in Australia. Our key findings are that the post-2013 changes to Australian aid have had wide-ranging impacts and have led to deteriorating overall aid quality. However, changes have not affected all aspects of the aid program equally, and some changes are starting to be reversed. In discussion, we examine what these developments mean for the future of Australian aid.

  8. Decision aiding in public policy generation and implementation: a multicriteria approach to evaluate territorial resilience

    Directory of Open Access Journals (Sweden)

    Maria Franca Norese

    2016-12-01

    Full Text Available A decision aid process should be the result of an interaction between analysts, decision makers and stakeholders. Decision aiding is sometimes required when the problem situation is new and a formal decision system does not exist. Its role becomes that of facilitating the Intelligence phase of a decision process. In other situations, a criticism of certain policy making processes and their use of data, which may be available in institutional databases or are required as indicators for the decision process, motivates an intervention oriented towards structure knowledge and improvements of these processes. A preliminary study, which includes modelling and application of multi-criteria methods, can clarify a complex and new situation, propose a consistent approach for the later phases of a decision process or propose a different and more effective use of the data. A case study is proposed here to describe this methodological approach in relation to the disaster resilience of municipalities near the mbrone River, in Tuscany (Italy.

    1986-01-01

    Control systems are typically implemented using conventional PID controllers, which are then tuned manually during plant commissioning to compensate for interactions between feedback loops. As plants increase in size and complexity, such controllers can fail to provide adequate process regulations. Multivariable methods can be utilized to overcome these limitations. At the Chalk River Nuclear Laboratories, modern control systems are designed and analyzed with the aid of MVPACK, a system of computer programs that appears to the user like a high-level calculator. The software package solves complicated control problems, and provides useful insight into the dynamic response and stability of multivariable systems

    The Internet is a major source of HIV-related information and resources for persons recently diagnosed with HIV/AIDS (PRDHA). This study examined the types of HIV-related websites that appear as a result of HIV-related keyword searches and the extent to which website information targets PRDHA. The first page of HIV-related webpages from 18 keyword searches was coded. Among 137 webpages meeting inclusion criteria, 63% represented HIV-informational websites, 31% targeted HIV-positive individuals, and over half contained or provided access to HIV prevention, treatment, and transmission information. Thirty-three percent of webpages contained or provided access to PRDHA-targeted information, with a greater percentage of those webpages having mobile, non-English, and "Ask the Expert" features compared with non-PRDHA targeted webpages. Implications for PRDHA include the following: (1) they should explore HIV-related websites to gain insight into the credibility of the information contained on those sites; (2) PRDHA must be aware that HIV-related websites have the potential to elicit dated, emotionally distressing, or irrelevant information; and (3) to obtain information that relates to their demographic and situational profile, they may wish to use specific key terms (e.g., "HIV women") rather than attempting to navigate webpages that arise from general search terms (e.g., "HIV"). Recommendations for future development of online resources for PRDHA include providing HIV-relevant information in a stepwise fashion, providing demographically targeted HIV information, and greater utilization of mobile technology.

    2005-01-01

    This article utilizes data from the Equal Employment Opportunity Commission's Integrated Mission System database to document the levels of employment discrimination involving individuals with HIV/AIDS. The researchers explore the theory that the nature of HIV/AIDS related employment discrimination is rooted in deeper stigmatization than discrimination against other disability groups. Researchers compare and contrast key demographic characteristics of Charging Parties and Respondents involved in HIV/AIDS related allegations of discrimination and their proportion of EEOC merit resolutions to those of persons with other physical, sensory, and neurological impairments. Findings indicate that, in contrast to the general disability group, HIV/AIDS was more likely to be male, ethnic minorities, between the ages of 25-44, in white collar jobs, in the South and West and to work for businesses with 15 to 100 employees. Additionally, the allegations in HIV/AIDS were more likely to receive merit resolution from the EEOC by a large difference of ten percent.

  14. Personality and the subjective assessment of hearing aids.

    1999-01-01

    Relatively little is known about the influence of patients' personality features on the responses they make to self-assessment items used to measure the outcome of a hearing aid fitting. If the personality of the hearing aid wearer has a significant influence on self-report outcome data, it would be important to explore the relevant personality variables and to be cognizant of their effects when using subjective outcome data to justify decisions about clinical services or other matters. This investigation explored the relationship between several personality attributes and responses to the Abbreviated Profile of Hearing Aid Benefit (APHAB). It found that more extroverted patients tend to report more hearing aid benefit in all speech communication situations. In addition, patients with a more external locus of control tend to have more negative reactions to loud environmental sounds, both with and without amplification. Anxiety also played a small additional role in determining APHAB responses. Although personality variables were found to explain a relatively small amount of the variance in APHAB responses (usually around 10%), these outcomes should alert practitioners and researchers to the potential effects of personality variables in all self-report data.

    Though race and region are not by themselves risk factors for HIV infection, regional and racial disparities exist in the burden of HIV/AIDS in the US. Specifically, African Americans in the southern US appear to bear the brunt of this burden due to a complex set of upstream factors like structural and cultural influences that do not facilitate HIV/AIDS awareness, HIV testing, or sexual risk-reduction techniques while perpetuating HIV/AIDS-related stigma. Strategies proposed to mitigate the burden among this population have included establishing partnerships and collaborations with non-traditional entities like African American churches and other faith-based organizations. Though efforts to partner with the African American church are not necessarily novel, most of these efforts do not present a model that focuses on building the capacity of the African American church to address these upstream factors and sustain these interventions. This article will describe Project Fostering AIDS Initiatives That Heal (F.A.I.T.H), a faith-based model for successfully developing, implementing, and sustaining locally developed HIV/AIDS prevention interventions in African American churches in South Carolina. This was achieved by engaging the faith community and the provision of technical assistance, grant funding and training for project personnel. Elements of success, challenges, and lessons learned during this process will also be discussed.

    Full Text Available Individuals infected by HIV are at an increased risk for developing non-Hodgkin's lymphomas (AIDS-NHL. In the highly active antiretroviral therapy (HAART era, there has been a significant decline in the incidence of AIDS-associated primary central nervous system lymphoma (PCNSL. However, only a modest decrease in incidence has been reported for other AIDS-NHL subtypes. Thus, AIDS-NHLs remain a significant cause of morbidity and mortality in HIV infected individuals. Recently, much attention has been directed toward the role of miRNAs in cancer, including NHL. Several miRNAs, including those encoded by the miR-17-92 polycistron, have been shown to play significant roles in B cell tumorigenesis. However, the role of miRNAs in NHL in the setting of HIV infection has not been defined.We used quantitative realtime PCR to assess the expression of miRNAs from three different paralog clusters, miR-17-92, miR-106a-363, and miR-106b-25 in 24 cases of AIDS-NHLs representing four tumor types, Burkitt's lymphoma (BL, n = 6, diffuse large B-cell lymphoma (DLBCL, n = 8, primary central nervous system lymphoma (PCNSL, n = 5, and primary effusion lymphoma (PEL, n = 5. We also used microarray analysis to identify a differentiation specific miRNA signature of naïve, germinal center, and memory B cell subsets from tonsils (n = 4. miRNAs from the miR-17-92 paralog clusters were upregulated by B cells, specifically during the GC differentiation stage. We also found overexpression of these miRNA clusters in all four AIDS-NHL subtypes. Finally, we also show that select miRNAs from these clusters (miR-17, miR-106a, and miR-106b inhibited p21 in AIDS-BL and DLBCL cases, thus providing a mechanistic role for these miRNAs in AIDS-NHL pathogenesis.Dysregulation of miR-17-92 paralog clusters is a common feature of AIDS-associated NHLs.

    Full Text Available Abstract Background HIV/AIDS is fast becoming a chronic disease with the advent of antiretroviral drugs, therefore making home based care key in the management of chronically ill HIV/AIDS patient. The objective of this study was to determine the perception and practice of health care workers on HIV/AIDS related home based care in the health facilities in Ogun state, Nigeria. Methods This study is an analytical cross-sectional study. A multistage cluster sampling technique was used to obtain a representative sample of the primary health care workers in Ogun state. An interviewer administered structured questionnaire was administered by trained health workers to elicit the required information. Result A total of 350 health care workers were interviewed, 70% of the respondents could adequately describe the components of home based care. Only 38.7% were aware of the National guideline on home based care practices and 17.1% believe that home based care will not significantly improve the prognosis of PLWAs. Few 19.1% had ever been trained or ever involved 16.6% in home based care practices. Only 20 [5.7%] are involved on a weekly basis, 16 [4.6%] monthly and 22 [6.3%] quarterly. Reasons given for non implementation of home based care are inadequate number of healthcare workers 45%, lack of political will 24.4%, lack of implementation by facility managers 14% and inadequate funds 16.6%. Factors that were significantly associated with the practice of home based care were perception of its relevance in improving prognosis [OR = 54.21, C.I = 23.22-129.52] and presence of a support group in the facility [OR = 4.80, C.I = 2.40-9.57]. There was however no statistically significant relationship between adequate knowledge of home based care [OR = 0.78, C.I = 0.39-1.54] and previous training on home based care (OR = 1.43, C.I = 0.66-3.06]. Conclusion The practice of home based care for HIV/AIDS among the study population is low

    The study of active and healthy aging is a primary focus for social and neuroscientific communities. Here, we move a step forward in assessing electrophysiological neuronal activity changes in the brain with healthy aging. To this end, electroencephalographic (EEG) resting state activity was acquired in 40 healthy subjects (age 16–85). We evaluated Fractal Dimension (FD) according to the Higuchi algorithm, a measure which quantifies the presence of statistical similarity at different scales in temporal fluctuations of EEG signals. Our results showed that FD increases from age twenty to age fifty and then decreases. The curve that best fits the changes in FD values across age over the whole sample is a parabola, with the vertex located around age fifty. Moreover, FD changes are site specific, with interhemispheric FD asymmetry being pronounced in elderly individuals in the frontal and central regions. The present results indicate that fractal dimension well describes the modulations of brain activity with age. Since fractal dimension has been proposed to be related to the complexity of the signal dynamics, our data demonstrate that the complexity of neuronal electric activity changes across the life span of an individual, with a steady increase during young adulthood and a decrease in the elderly population.

    Non-Hodgkin's lymphoma (NHL) remains the second most common malignant complication in patients with human immunodeficiency virus (HIV) infection. Even though NHL is commonly chemosensitive to primary treatment, failure or relapse still occurs in a large number of patients. We conducted this retrospective study to evaluate the efficacy and safety of gemcitabine, dexamethasone, and cisplatin (GDP) for relapsed or refractory AIDS-related NHL (AIDS-NHL). Forty-eight patients with relapsed or refractory AIDS-NHL were treated with intravenous combination chemotherapy with GDP. The overall objective response rate was 54.1% (95% confidence interval, CI, 40.1-68.3%), with 10 complete responses and 16 partial responses. The 2-year overall survival rate (OS) was 70.8% (95% CI 58.0-83.7%), and the 5-year OS was 41.7% (95% CI 27.7-55.6%). The 2-year progression-free survival rate (PFS) was 37.5% (95% CI 23.8-51.2%), and the 5-year PFS was 25.0% (95% CI 12.8-37.3%). The median progression-free survival was 8.8 months (95% CI 0-20.3 months), and the median overall survival was 40.6 months (95% CI 22.6-58.6 months). Patients with B cell tumors who relapsed but had no B symptoms were clinical stage I/II, had infiltration fewer than two extranodal sites, had CD4⁺ counts >200 cells/μL, and had lactate dehydrogenase (LDH) less than the upper limit of normal benefited from GDP. The level of LDH had a significant impact on the response rate to chemotherapy with GDP (P = 0.015). Myelosuppression was the main side effect; the incidence of grade 3-4 anemia was 8.3%; leukopenia, 37.5%; and thrombocytopenia, 48.3%. Univariate and multivariate analyses were performed to determine variables for OS and PFS. This study confirms that GDP is an effective and safe salvage regimen in relapsed or refractory AIDS-NHL, was associated with modest declines in CD4⁺ lymphocyte counts, and did not promote HIV-1 viral replication.

    Full Text Available The acceptability of hearing aids in people with presbyacusis has been improved but assessment of whether there is a need for more counseling to increase the number of regular hearing-aid users seems to be important. The aim of this study was to determine if the hearing aid was worn regularly and over a long period of time in people with presbyacusis. A questionnaire survey of patients with presbyacusis who had been fitted with a monaural behind the ear hearing aid for the first time was undertaken. The patients were divided into four groups ranging from 6 months to 3 years after fitting. Overall regular long-term use of the hearing aid was found in the majority of patients with presbyacusis. The main dropout point was within the first year after fitting the hearing aid. The study furthermore revealed a relatively high demand for further help and advice with the hearing aid in all groups.

    Full Text Available Background: Inadequate funding for health is a challenge to attaining health-related Millennium Development Goals. Significant increase in health funding was recommended by the Commission for Macroeconomics and Health. Indeed Official Development Assistance has increased significantly in Uganda. However, the effectiveness of donor aid has come under greater scrutiny. This paper scrutinizes the prerequisites for aid effectiveness. The objective of the study was to assess the prerequisites for effectiveness of donor aid, specifically, its proportion to overall health funding, predictability, comprehensiveness, alignment to country priorities, and channeling mechanisms. Methods:Secondary data obtained from various official reports and surveys were analyzed against the variables mentioned under objectives. This was augmented by observations and participation in discussions with all stakeholders to discuss sector performance including health financing. Results:Between 2004−2007, the level of aid increased from US$6 per capita to US$11. Aid was found to be unpredictable with expenditure varying between 174−360 percent from budgets. More than 50% of aid was found to be off budget and unavailable for comprehensive planning. There was disproportionate funding for some items such as drugs. Key health system elements such as human resources and infrastructure have not been given due attention in investment. The government’s health funding from domestic sources grew only modestly which did not guarantee fiscal sustainability. Conclusion: Although donor aid is significant there is need to invest in the prerequisites that would guarantee its effective use.

    This paper investigates whether aid flows to developing countries fit well with their development priorities. In particular, we examine aid allocation across sectors in a given recipient country by using sectoral data on aid and indicators that measure the recipient's need for aid in each sector. The data show that inter-recipient aid allocation reflects the recipient's need. However, we found no evidence that inter-sectoral allocation fits with national priorities except in high- and middle-...

    Strabismus is a pathology that affects approximately 4 % of the population, causing aesthetic problems reversible at any age and irreversible sensory alterations that modify the vision mechanism. The Hirschberg test is one type of examination for detecting this pathology. Computer-aided detection/diagnosis is being used with relative success to aid health professionals. Nevertheless, the routine use of high-tech devices for aiding ophthalmological diagnosis and therapy is not a reality within the subspecialty of strabismus. Thus, this work presents a methodology to aid in diagnosis of syndromic strabismus through digital imaging. Two hundred images belonging to 40 patients previously diagnosed by an specialist were tested. The method was demonstrated to be 88 % accurate in esotropias identification (ET), 100 % for exotropias (XT), 80.33 % for hypertropias (HT), and 83.33 % for hypotropias (HoT). The overall average error was 5.6Δ and 3.83Δ for horizontal and vertical deviations, respectively, against the measures presented by the specialist.

    Many heterosexuals have not altered their sexual practices in response to the threat of Acquired Immune Deficiency Syndrome (AIDS). Knowledge of risk alone appears to have little effect on altering sexual behavior; more complex psychological factors seem to be involved. Condom use to prevent the spread of Human Immunodeficiency Virus is a unique…

  16. Consultation on AIDS and the workplace.

    Science.gov (United States)

    1988-12-01

    The 1988 Consultation on Acquired Immunodeficiency Syndrome (AIDS) and the Workplace, organized by the World Health Organization (WHO), addressed 3 issues: 1) risk factors associated with human immunodeficiency virus (HIV) infection in the workplace, 2) the response of businesses and workers to the AIDS epidemic, and 3) use of the workplace for AIDS education. There is no evidence to suggest that HIV can be transmitted by casual, person-to-person contact in the workplace. The central policy issue for businesses concerns protection of the human rights of workers with HIV infection. Most workers with HIV/AIDS want to continue working as long as they are able to, and they should be enabled to contribute their creativity and productivity in a supportive occupational setting. Consistent policies and procedures should be developed at national and enterprise levels before HIV-related questions arise in the workplace. Such policies should be communicated to all concerned, continually reviewed in the light of scientific and epidemiologic evidence, monitored for their successful implementation, and evaluated for their effectiveness. Pre-employment HIV/AIDS screening, whether for assessment of fitness to work or for insurance purposes, should not be required and raises serious concerns about discrimination. Moreover, there should be no obligation on the worker's part to inform his or her employer if HIV infection develops. Information and educational activities at the workplace are essential to create the climate of collective responsibility and mutual understanding required to protect individuals with HIV or AIDS from stigmatization and discrimination by co-workers, employers or clients, and unions.

    For patients with chronic kidney disease (CKD) who are progressing to end-stage kidney disease (ESKD) a decision of whether to undertake dialysis or conservative care is a critical component of the patient journey. Shared decision making for complex decisions such as this could be enhanced by a decision aid, a practice which is well utilised in other disciplines but limited for nephrology. A multidisciplinary team in Australia and New Zealand (ANZ) utilised current decision-making theory and best practice to develop the 'My Kidneys, My Choice', a decision aid for the treatment of kidney disease. A patient-centred, five-sectioned tool is now complete and freely available to all ANZ units to support the ESKD education and shared decision-making process. Distribution and education have occurred across ANZ and evaluation of the decision aid in practice is in the first phase. Development of a new tool such as an ESKD decision aid requires vision, multidisciplinary input and ongoing implementation resources. This tool is being integrated into ANZ, ESKD education practice and is promoting the philosophy of shared decision making. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.
